DNS - a distributed database of information used to translate domain names into the numerical Internet Protocol (IP) addresses.

is a distributed database system that establishes one or more name servers to maintain mappings between IP addresses and names.

The DNS is the hierarchical system by which easy-to-remember, human-friendly names like "yahoo.com" are associated with Internet locations

The DNS plays a large role in making the internet what we know it as today. The DNS is a model for tracking other machines that contain web sites and their numeric IP addresses, then it translates the domain names (www.me.com into 243.290.93.210) from name to IP. When a domain name is purchased it is assigned an IP address by which it is recognized by other machines in the DNS server.

n. In the Internet suite of protocols, the distributed database system used to map domain names to IP addresses.

an automatic Internet phone book, translating an easy-to-remember domain name like hei.ca to its Internet address like 69.6.238.89 and vice-versa.

Like using a telephone book, a system of looking up computer names in order to obtain their IP number. Each computer in the system is known as a Domain Name Server and maintains a list of local computers and their IP numbers.

A distributed database of information that is used to translate domain names into Internet Protocol (IP) numbers. In other words, computers need numbers in order to function. The computer itself does not care whether you are yahoo.com or google.com. It has no idea how to find the name, it needs a number that identifies that name. So when you buy a domain, say www.whatever.com, it is nothing until you get it hosted somewhere and until that host assigns a number to your domain. A good analogy of this would be social security numbers and humans. Humans are identified primarily by their names, but government organizations use social security numbers to identify the person behind that name.

The Domain Name System, or DNS, is a system by which one Internet host can find another so it can perform routine Internet activities like email, FTP, and World Wide Web.

Sometimes referred to as the BIND service in BSD UNIX, DNS offers a static, hierarchical name service for TCP/IP hosts. The network administrator configures the DNS with a list of host names and IP addresses, allowing users of workstations configured to query the DNS to specify remote systems by host names rather than by IP addresses. For example, a workstation configured to use DNS name resolution can use the command

1. The on-line distributed database system used to map domain names to Internet addresses. 2. (IRM) A generic name referencing a location on the TCP/IP network. A DNS server manages DNS names.

Database of information that is used to translate domain names, into Internet Protocol (IP) numbers. The IP numbers what computers look for to find each other on the Internet.

A standard system of addressing for the Internet that hostnames follow.

A system used by computers on the Internet to translate computer ("host") names into IP addresses. When you are browsing the Internet and you want to connect to a specific machine (Web server), you simply type its domain name in the address window of your computer's browser. For example, if you were looking for DSL-Experts.com, you would simply type www.DSL-Experts.com into the address window of your browser. Domain names usually consist of the name of an organization, followed by a period (called a "dot"), and an ending abbreviation signifying the type of the organization, such as: .com: Commercial Organization .edu: Educational Institution .gov: Government Organization .int: International Organization .mil: United States Military .net: Internet Service Provider .org: Non-Profit Organization Sample domain names include DSL-Experts.com, Verizon.com and DSL.edu. Web sites located outside the United States use domain names that end in abbreviations indicating the country of origin. (For example, .uk for the United Kingdom, and .mx for Mexico.)

The distributed system that provides a translation service between names and IP addresses. It is described in RFC 1035. HELO

Internet service that translates domain names into IP addresses. The Internet is based on IP addresses, not names. When a domain name is entered into your browser, or domain email is sent or received, a DNS service must translate the name into the corresponding IP address. Without domain name service, your domain email, or your web pages cannot be found on the Internet.

Every server on the internet can be identified by an IP address, these consist of a series of digits. Since a series of digits isn't easy to remember, the Domain Name System was created. This maps a 'user friendly' name to the IP address.

A method for locating and translating domain names on the Internet and on private TCP/IP networks. DNS provides a service for mapping DNS domain names to IP addresses and vice versa. This allows applications, computers, and users to query DNS to identify a remote system by fully qualified domain names instead of by IP addresses. See also IP address.

Rules for structuring Internet addresses in the following way: User [email protected]

the distributed host and network name database system used to translate between Internet addresses and their associated host and network names. RFC 1034 is an introduction to DNS. RFC 1035 describes the protocols and data types used.

The DNS is a distributed database that provides information about Internet hosts. Note: www.aunic.net First, second and third level names This refers to the three parts to a domain name from right to left. For example IntaServe.com.au has as it's first level Au, it's second level .com and it's third level name domain-names.

A protocol and naming system used throughout the Internet to map Internet Protocol (IP) addresses to user-friendly names. DNS is sometimes referred to as the BIND service.

A distributed database of information that translates easy to remember domain names into Internet Protocol (IP) numbers, which are used by computers to locate each other on the Internet. The DNS comprises computers, data files, software, and people working together.

Hierarchical system by which easy-to-remember, text-based names such as "pir.org" are associated with numeric Internet locations. EPP: See Extensible Provisioning Protocol.

DNS precision.com.fj is a domain name. Every Internet address must be unique and is assigned a number. Precision IT''s Home page is located at 202.125.41.66 this is called our IP address. When you use our domain name (www.precision.com.fj) you are in fact accessing this IP address, this is called the Domain Name System.

A program that translates URLs to IP addresses by accessing a database maintained on a collection of Internet servers. The program works behind the scenes to facilitate surfing the Web with alpha versus numeric addresses.

DNS allows the use of host and domain names to refer to hosts, rather than IP addresses. DNS software handles the translation of names to numbers (used by computers for communications).

A system of computers and protocols on the Internet through which an Internet domain name is translated into an IP address.

(DNS) - Every server on the internet can be identified by its IP address, these consist of a series of digits, e.g. 195.182.176.1. It isn't easy to remember a series of digits for each web site you want to visit, so the Domain Name System was created. This maps a name to the IP address.

Aka domain name server. A way of identifying network addresses on the Internet or in LAN's; for example, allows a server to be named, or a website URL to be listed, rather than using an identifier like 225.225.225.10. It is easier to remember a domain name, rather than a number.

(DNS)- A scheme enabling computers on the Internet to translate their computer-friendly IP addresses into human-friendly strings of text (their "domain name, like my ISP's won " core. symnet.net") and back again. Not all Internet nodes have domain names; they do have IP addresses.

An Internet service that translates domain names in IP addresses. Used to resolve domain names to specific host computers.

The DNS is a general purpose distributed, replicated, data query service. The principal use is the lookup of host IP addresses based on host names. The style of host names now used in the Internet is called "domain name", because they are the style of names used to look up anything in the DNS. Some important domains are .COM (commercial), .NET (network), .EDU (educational), .GOV (government) and .MIL (military). Most countries also have a domain. For example, .US (United States), .UK (United Kingdom) and .AU (Australia).

Domain Name System (DNS) is a distributed Internet directory service. DNS is used mostly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be located and email delivery stalls.

(DNS) A distributed database, and the operating software, holding records associating domain names with IP addresses. Most ISPs run DNS for their customers, the records held allow a computer somewhere else on the Internet making an enquiry of the DNS server to find the translation from a human friendly domain name to an IP address that is understandable by a computer, e.g. www.euro-ix.net to 193.194.136.2.

This is a hierarchical naming scheme for Internet computers, allowing Internet packets to be sent to a top-level domain first, and then to a subdomain, and finally to an individual computer. It's like the postal system -- where the zip code is the top-level domain, the carrier route is the subdomain, and the street address is the individual computer. One computer in each domain (the "Domain Name Server") forwards along the messages it receives from outside the domain.

DNS is a service that translates domain names into IP addresses in much the same way as someone might find your telephone number by first referencing your name in the listings. There is no single DNS database. DNS is actually a network of DNS servers that share information with each other.

The Domain name system comprises of distributed databases of information that are used to translate domain names into Internet Protocol (IP) numbers. Individual computers/name servers around the world hold a portion of the global database, which is accessible by all computers and users on the Internet.

System of converting numeric IP address to domain names and back again.

The system by which Internet sites are given an identifying number (IP number) as well as an easier-to-remember domain name. ICANN is in charge of administering the DNS.

A collection of distributed databases (domain name servers) that maintain the correlation between domain name addresses and numerical Internet protocol (IP) addresses.

A set of guidelines and rules developed by the Internet community at large, which allows the use of both domain name addresses (such as bluestem.prairienet.org) and IP addresses (such as 192.12.3.4) to navigate the Internet. The domain name address is used by human users and is automatically translated into the numerical IP address, which is used by packet-routing software.

Allows users to relate to computers on the Internet by using textual addresses (e.g. ww.mimograph.com) for ease of use, rather than the IP Address system (69.222.0.22).

System that makes it easier to get to Web sites by translating their numerical addresses into names. For example, when you type "www.duke.edu" in your browser, DNS translates that to a number and retrieves the site. Duke's DNS numbers - 152.3.250.1 and 152.3.250.2

The Internet was built on the notion that any computer on a global network can be identified by its numeric Internet Protocol (IP) address. But since people, and not machines, are the primary users of the Internet, a more people-friendly naming system called the Domain Name System (DNS) was invented. DNS maps a host name like www.opensrs.org to the IP address of the machine that hosts the OpenSRS web site. For example, DNS actually maps the host name www.opensrs.com to the IP address 207.136.98.175 DNS is built upon the notion that some server's are 'authoritative' (meaning, knows all there is to know) for certain domains. A distributed name server hierarchy, beginning with the A Root Server and ending at the thousands of nameservers active on the Internet, ensures that the naming and directing system works the same from anywhere.

DNS missinglink.com.au is a domain name. Every Internet address must be unique and is assigned a number. The Missing Link's Home page is located at 61.88.7.228 this is called our IP address. When you use our domain name (www.missinglink.com.au) you are in fact accessing this IP address, this is called the Domain Name System.

The system that translates Internet domain names or URLs (e.g.: wwwmil.rades.af.mil) into IP addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet IP address.

The Domain Name System (DNS) translates easily remembered textual names, such as www.radiant.net, into numerical IP addresses, such as 207.194.200.18, allowing for easier Internet use

The naming service used on the Internet to provide standard naming conventions for IP computers.

Database that links IP addresses and domain names. See also domain name, IP.

Internet domain name are located and translated into Internet Protocol addresses by DNS. A domain name is used to replace an digit Internet address with a meaningful and easy-to-remember word.

The distributed name and address mechanism used in the Internet. This mechanism allows you to map a domain name to an IP address, allowing you to look up a site by domain name without knowing the IP address of the site. DNS also allows reverse lookup, letting you get a machine's IP address from its name. DPMS

A hierarchical naming system used for locating domain names on the Internet and on private TCP/IP networks. DNS provides a service for mapping DNS domain names to IP addresses, and vice versa. This allows users, computers, and applications to query the DNS to specify remote systems by fully qualified domain names rather than by IP addresses. See also domain; Ping.

The DNS is a static, hierarchical name service used with TCP/IP hosts, and is housed on a number of servers on the Internet. Basically, it maintains a database for figuring out and finding (or resolving) host names and IP addresses on the Internet. This allows users to specify remote computers by host names rather than numerical IP addresses The advantage of the DNS is that you don't have to remember numerical IP addresses for all the Internet sites you want to access.

Internet service that maps Internet domains into corresponding IP addresses. DNS database is distributed and replicated among many DNS servers, so when you change your domain's IP address, the changes take a while to propagate.

The matching of host names to IPs.

DNS is the Domain Name System, which is the system by which Web sites are named and mapped to IP addresses. See also domain name and IP address.

The organized arrangement of domain names on the Internet.

The domain name system (DNS) is the way that Internet domain name are located and translated into Internet Protocol addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet address. Because maintaining a central list of domain name/IP address correspondences would be impractical, the lists of domain names and IP addresses are distributed throughout the Internet in a hierarchy of authority. There is probably a DNS server within close geographic proximity to your access provider that maps the domain names in your Internet requests or forwards them to other servers in the Internet.

A system of servers that route email and enable Internet connections. The major, top-level DNS servers feed updated DNS information to smaller subordinate DNS servers, which in turn hold more detailed information on specific areas of coverage. Because no single DNS server has all the address information of the Internet, successful routing may require routing through several levels of servers.

(DNS) The Internet naming scheme which consists of a hierarchical sequence of names, from the most specific to the most general (left to right), separated by dots, for example nic.ddn.mil. (See also: IP address)

hierarchical naming system used to locate computers on the Internet, matching the number by which one networked computer recognizes another (the IP number) to a name which assigns the computer owner to a domain or category of user. Top-level domains are indicated by the abbreviations at the end of the name. For countries outside the US, top-level domains are countries ( uk, au, fr). Within the US at the top-level and at the second level elsewhere, domain names describe degree-awarding universities ( edu in the US, ac in the UK), commercial organizations ( com, co), government agencies ( gov), non-profit and charitable organizations ( org), etc. The next level down, and often the first element of the name, is the name or alias of an organization or individual. For example, Inclusive Technology’s Internet identity inclusive.co.uk is inclusive (name of organization) co (type of organization) uk (country).

The domain name system (DNS) translates human-readable computer names, like http://csrc.nist.gov, to the numeric IP addresses used by computers. For more information, see: http://www.whatis.com/dns.htm.

Name resolution software that translates alphabetic site names into numeric IP addresses. The DNS server maintains a database of site names and their corresponding IP addresses.

DNS is the mechanism by means of which text names such as www.wifi-italia.com are translated to numerical Internet Protocol (IP) addresses such as 192.100.68.211. Humans prefer (and can remember) the text names but internally the Internet communicates numerically.

The distributed and hierachical information system that allows, among many other things names such as www.foobar.example to be translated into IP addresses and back. The general concepts of the DNS are described in RFC 1034.

How computer networks locate Internet domain names and translate them into IP addresses. The domain name is the actual name for an IP address or range of IP addresses. E.g. MarketingSherpa.com. See reverse DNS.

Short for Domain Name System (or Service), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.mydomain.com might translate to 198.105.232.4. Also See IP Address

A general-purpose distributed, replicated, data query service chiefly used on the Internet for translating hostnames into Internet addresses. Also, the style of hostname used on the Internet (though such a name is properly called a fully qualified domain name). DNS can be configured to use a sequence of name servers, based on the domains in the name being looked for, until a match is found. The Domain Name System refers to both the way of naming hosts and the servers and clients that administer that information across the Internet.

A hierarchical name service for TCP/IP hosts (sometimes referred to as the BIND service in BSD Unix). The network administrator configures the DNS with a list of hostnames and IP addresses, allowing users of workstations configured to query the DNS to specify the remote systems by hostnames rather than IP addresses. DNS domains should not be confused with Windows NT domains.

A Domain Name Server maps IP numbers to a more easily remembered name. When you type http://www.webguest.com into your browser, the DNS (specified when you installed dial-up networking) searchs for a matching IP address (208.28.202.95). If the DNS doesn't find an entry in its database, it will ask other DNSs until the entry is found, and you will see our site. Otherwise, you'll get an error message from your browser.

A model for tracking other machines (that contain web sites) and their numeric IP addresses. It translates domain names (for example, www.rackspace.co.uk into a numerical IP address). When a computer is referred to by name, a domain name server puts that name into the numeric IP address assigned to that computer. So when you buy a domain, say www.yourname.com, it does not become accessible until it gets assigned an IP address from a hosting company. Once the IP address is assigned, a cross-reference record (DNS record) is created that points your domain name to the numeric IP address.

A database system which looks up host IP addresses based upon domain names. For example if you ask for "www.thisismyhost.com" it will return "123.45.67.89".

The unique name of a collection of computers connected to a network such as the Internet. A replicated, distributed data query service for looking up host IP addresses based on host names. The DNS is hierarchical, consisting of domains, subdomains, sites, and hosts. Unique names are formed from smallest to largest, and are of the form [email protected], where host and site are often optional. On the Internet, domain names typically end with a suffix denoting the type of site:.com (commercial).edu (educational).net (network operations).gov(US government).mil (US military).org (organization).us (United States).ca (Canada).uk (United Kingdom).au (Australia.cz (Czech Republic).xx(where xx refers to another country's two-letter abbreviation)

uses a hierarchy of named domains (subdivisions of computers) to make things more intuitive.

Service that maps node names to IP addresses.

The way that nameservers translate Internet domain names to the corresponding IP addresses.

A hierarchical naming system for identifying Transmission Control Protocol/Internet Protocol (TCP/IP) hosts on the internet.

The method by which Internet addresses (such as "mit.edu") are converted into computer-readable IP addresses (such as "182.156.12.24"). DNS is one of the most flexible, powerful technical features of the Internet, letting computers appear and disappear from the Internet without causing problems. DNS also makes sending messages much easier, because all names do not have to be in a central repository.

An Internet addressing system that uses a group of names that are listed with dots (.) between them, working from the most specific to the most general group. In the United States, the top (most general) domains are network categories such as edu (education), com (commercial), and gov (government). In other countries, a two-letter abbreviation for the country is used, such as ca (Canada) and au (Australia).

Domain Name System. DNS servers are located at many strategic places on the nets to resolve the routing of e-mail and Internet connections. There are thirteen major, top-level DNS servers, which are updated daily, and these in turn feed the updated DNS information to smaller subordinate DNS servers, which hold more detailed information on their specific areas of coverage. No single DNS server has all the address information of the Internet, and successful routing may require routing through several levels of servers.

Name resolution software that lets users locate computers on a UNIX network or the Internet (TCP/IP network) by domain name. The DNS root name servers maintain a database of domain names (host names) and their corresponding IP addresses and are responsible for one or more top-level domain names, e.g., com or edu.

A distributed shared database that includes information about canonical names and alias names of computers and IP addresses.

The DNS is a unique name of a collection of computers connected to networks such as the Internet, where domain names typically end with a suffix denoting the type of site: like .com (for commercial), .edu (educational), .net (network operations), .gov (government) or .in (India).

The system responsible for translating domain names into numeric IP addresses. The DNS maintains a list of all the domain names and distributes them throughout the world. Way2Host can assist you in registering and transferring your domain name.

The online distributed database system that is used to map human-readable addresses into Internet Protocol (IP) addresses.

(DNS) Used to resolve host names to IP addresses

A distributed database of information that is used to translate domain names, which are easy for humans to remember and use, into Internet Protocol (IP) numbers, which are what computers need to find each other on the Internet. People working on computers around the globe maintain their specific portion of this database, and the data held in each portion of the database is made available to all computers and users on the Internet. The DNS comprises computers, data files, software, and people working together.

A model for tracking other machines (that contain web sites such as http://www.yourname.com/) and their numeric IP addresses (###.###.##.###).Once the IP address is assigned, a cross-reference record (DNS record) is created that points your domain name to the numeric IP address. Once this is done, the web address is accessible by a browser over the internet.

The system that locates the IP (Internet Protocol) addresses that correspond to named computers and domains. A DNS name consists of a sequence of information separated by dots.

The DNS maintains a relationship between IP addresses and domain names. DNS is composed of a set of database servers which maintain the relationship between IP addresses and domain names and facilitate the lookup between the two. Computers use the DNS system to electronically transmit data with other computers through the internet.

The domain name system (DNS) provides a method of representing Internet Protocol (IP) address as text-based names. These are used as Web addresses (universal resource locators - URLs) . For example, www.microsoft.com is the representation of site 207.68.156.58.Domain names are split into: Top Level domains or Global (or generic) top level domain names (gLTD) such as . com or . co.uk Second-level domain. This refers to the company name and is sometimes referred to as the enterprise name, e.g. novell.com. Third-level or sub-enterprise domain. This may be used to refer to an individual server within an organisation such as support.novell.com.

The Domain Name System (DNS) is a distributed database used by TCP/IP applications to map between hostnames and IP addresses, and to provide electronic mail routing information. Each site maintains its own database of information and runs a server program that other systems across the Internet can query. The DNS provides the protocol, which allows clients and servers to communicate with each other. When you type http://www.matrixdm.com into your browser, the DNS (specified when you installed dial-up networking) searches for a matching IP address. If the DNS doesn't find an entry in its database, it will ask other DNS's until the entry is found, and you will see our site. Otherwise, you'll get an error message from your browser.

A system for translating numeric Internet addresses into strings of word segments denoting user names and locations.

A database system that translates an IP address into a domain name. For example, a numeric address like 232.452.120.54 can become something like xyz.com

An Internet service that translates the domain names used by people into the numeric IP addresses used for routing on the Internet. The domain name system is actually a network of domain name (DNS) servers.

A protocol and computer-naming hierarchy used throughout the Internet to map computer IP addresses to their domain name.

The Domain Name System (DNS) allows users to visit computers on the Internet by a name rather than a harder-to-remember IP address. The DNS, started in the mid-80s, is a distributed database containing records that allow users to input another computer's Domain name, which your computer then converts to the other computer's IP address. The DNS has a hierarchical structure, with each name composed of a series of "labels" separated by dots. (see IP Address below) The rightmost label in a name refers to the name's top-level Domain (such as .org). Each top-level Domain can be divided into many second-level Domains (such as icann.org). Second-level Domains can be divided into third-level Domains (such as www.icann.org and members.icann.org), and so on. Rule of thumb: the DNS system uses primarily words, the IP system uses only numbers. GLOSSARY DOMAINS WORDS CUBA

A service that converts symbolic node names to IP addresses. DNS is frequently used with TCP/IP. DNS uses a distributed database.

Database system that translates an IP address into a domain name. For example, a numeric address like 205.206.106.50 is converted into wwli.com.

A system for naming computers and network services that is organized into a hierarchy of domain. DNS is used in TCP/IP networks to locate computers through user-friendly names. DNS resolves a friendly name into an IP address, which is understood by computers. In Net8, DNS translates the host name in a TCP/IP address into an IP address.

(DNS) - A system by which one Internet host can find another. DNS translates words (Domain Names) into numbers that Internet computers can understand.

This is the Internet standard that matches names such as www.mcafee.com to the IP address that routes packets to an Internet-connected computer.

The naming service used by Internet Mail to support message routing. It maps domain addresses to IP addresses so Internet messages can be delivered to a particular server.

Every server on the internet can be identified by its IP (Internet Protocol) address. These consist of a series of digits, e.g. 212.84.187.11 It isn't easy to remember a series of digits for each web site you want to visit, so the Domain Name System was created. This maps a name to the IP address. .gif Image file, Graphic Interchange Format, usually used for graphics, logos etc

A database system which stores both the domain name and IP addresses of Internet computers. When you specify a domain name in your browser, it will access a DNS database to find the corresponding IP address then establish a connection to the site.

Allows users to relate to computers on the Internet by using textual addresses (eg. www.hscgroup.co.uk) for ease of use, rather than the IP Address system.

It is the database that translates text addresses (mycompany.com) into a numeric Internet address. This prevents you from having to remember lots of number for Internet addresses such as 156.46.57.10

a system that maps uniquely hierarchical names to specific Internet addresses

An Internet service that translated domain names into the corresponding IP address. Humans like domain names because they are easier to remember. For the Internet to work, however, the actual IP address must be known. Hence, the need for the translation from domain name to IP address.

The DNS translates URL text addresses (such as www.companyname.com) into a numeric Internet address (such as 202.215.12.1).

(DNS) The Internet's distributed service for translating host names into IP addresses.

These are servers that are located at many strategic places on the Internet they resolve the routing of email and Internet connections. This is also known as the system of converting IP Addresses to names and back again.

If you own your own domain name and you want to get your site hosted by someone, you have to login to the domain name manager and change the DNS to your host's DNS. For example if you were hosted by PokeZam.com and you had a domain name, your DNS would be ns1.pokezam.com and ns2.pokezam.com. By changing the DNS, it points your domain to your host, which in turn makes your site work.

an automatic Internet phone book, translating an easy-to-remember domain name like acleris.com to its Internet address like 71.18.25.37 and vice-versa.

The system that translates between Internet IP addresses and Internet host names.

The hierarchical referencing system by which easy-to-remember domain name addresses (such as "mycompany.com") are mapped to numeric IP addresses (such as "123.123.4.5") on the Internet. Note that the acronym DNS can stand for both Domain Name System and Domain Name Service.

DNS is an Internet service that translates domain names into IP addresses. A DNS server keeps a database of host computers, their respective domain names, and IP addresses. When a domain name is requested, the DNS server uses this table to send the user to the proper IP address. The DNS system is really its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

The system of internet names and addresses.

The system that makes it possible for you to think in terms of names such as penguin.tidbits.com, whereas computers think in terms of 204.57.157.10.

An addressing system that enables websites on the Internet to be reached by a simple name rather than by an IP address or numbers. Examples of domain names include .org, .net, .com, .ca, .gov, and .edu.

A general-purpose data query service whose principal use is the lookup of host addresses based on host names. Important domains are .com (commercial), .edu (educational), .net (network), .gov (U.S. government), .mil (U.S. military) and .org (organization).

(DNS) See DNS.

The DNS is a general purpose distributed, replicated, data queryservice. The principal use is the lookup of host IP addressesbased on host names. The style of host names now used in theInternet is called "domain name", because they are the style ofnames used to look up anything in the DNS. Some important domainsare: .COM (commercial), .EDU (educational), .NET (networkoperations), .GOV (U.S. government), and .MIL (U.S. military).Most countries also have a domain. For example, .US (UnitedStates), .UK (United Kingdom), .AU (Australia). It is defined inSTD 13, RFCs 1034 and 1035. See also: Fully Qualified DomainName. DOMAIN NAME, DOMAIN NAME SERVER (DNS)ENTRY

System on the Internet that stores the domain names and their corresponding IP addresses. 2.8

A hierarchical, distributed database that contains mappings of DNS domain names to various types of data, such as IP addresses. DNS enables the location of computers and services by user-friendly names, and it also enables the discovery of other information stored in the database. See also: domain; service; Transmission Control Protocol/Internet Protocol (TCP/IP); IP address

On the Internet, the domain name system (DNS) stores and associates many types of information with domain names, but most importantly, it translates domain names (computer hostnames) to IP addresses. It also lists mail exchange servers accepting e-mail for each domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use.
