With subnetting, the class arrangement of an IP address is ignored. For example, a class C address no longer has to have 24 bits of network number and 8 bits of host ID. With subnetting, some of the host ID bits are converted into network number bits.
A means of making a splitting a single IP address into multiple network addresses. It is accomplished by mathematically combining an IP address with another set of numbers called a network mask. Subnetting increases the number of networks an organization can have but decreases the number of hosts that can be on each network.
Subnetting entails splitting a single IP address into multiple network addresses.
A technique used to maximize the number of networks available within a range (class) of addresses. See also Subnetwork.
The act of subdividing the address space of a TCP/IP network ID into smaller network segments, each with its own subnetted network ID.
Dividing any network class into multiple subnetworks.
A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100 would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons.
A technique used to impose a hierarchy on IP addresses that supports a form of area routing.
