ARP is a method determining a host's Ethernet address from its Internet address. The network receives the ARP request, and then names the IP address. Next, the machine at this address returns its physical address so the information can be sent to it. If supported by all hosts, Internet addresses can be independent of Ethernet addresses.
a method used to resolve higher level protocol addressing (such as IP) into the appropriate header data required for ATM; i.e., port, VPI, and VCI; also defines the AAL type to be used.
Provides the rules for mapping an IP address to a physical machine address, using a correlation table.
The TCP/ IP protocol used to dynamicaly bind a high level IP address to a low-level hardware address. ARP is used only across a single physical network and is dependant on the hardware broadcast capability of the underlying network hardware. Although ARP is aware of IP, conceptually it resides in a lower layer than IP, and IP treats it as part of the functionality provided by the underlying hardware. (See [ Comer, chapter 5])

A protocol designed for Ethernet that allows the MAC address associated to a network address (usually an IP address) to be known so the packet can be sent over Ethernet. Defined by IETF RFC826 & STD37.
This protocol is used to associate an IP address to a hardware MAC address. A request is broadcast on the local network to discover the MAC address for an IP address.
A TCP/IP protocol used to dynamically translate the IP address of a network host to its LAN hardware (MAC) address. This action is limited to LANs that support hardware broadcasts.
The protocol that translates Internet Protocol, or IP, addresses into physical network addresses. One of the many members of the TCP/IP protocol suite, ARP is a key player in the process that allows a packet of data addressed to a particular Internet host to find its destination. See also DNS, RARP, and TCP/IP.
The lnternet and TCP/IP protocol used to bind dynamically a high-level IP address, such as an lnternet address, to a low-level physical hardware address. ARP operates only across a single physical network and is limited to networks supporting hardware broadcast.
A protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network.
Address Resolution Protocol.
ARP is hardware broadcast table of information generated on each machine in a TCPIP LAN network containing the system IP address and its physical card hardware address.
A protocol, described in RFC 826, used to determine the hardware address of another computer on a network. ARP is used when a computer may know the destination computer's IP address, but does not know the destination computer's hardware address. The sender broadcasts an ARP packet and the device that recognizes its own IP address responds with the unknown hardware address.

(2006-09-21) Chris Limb ddress esolution rotocol. A protocol used to convert an IP address into a physical address (e.g. an ethernet address).
Each device on a network has at least two addresses: a media access control (MAC) address, and an Internet Protocol (IP) address. The MAC address is the address of the physical network interface card inside the device, and never changes for the life of the device. The IP address can change if the machine moves to another part of the network or the network uses DHCP. ARP, one of the IP protocols, is used to match, or resolve, an IP address to its appropriate MAC address (and vice versa). ARP works by broadcasting a packet to all hosts attached to an Ethernet. The packet contains the IP address the sender is interested in communicating with. Most hosts ignore the packet. The target machine, recognizing that the IP address in the packet matches its own, returns an answer.
