In computer networking, a subnet is a section of a network that has been partitioned from other subnets, as part of a larger IP network. Subnetting allows a network administrator to logically organize machines and workstations on a network with multiple clients by creating divisions of smaller subnets. The subnet ID identifies the subnetwork that follows the network ID and precedes the host ID, which indentifies users, or clients, of a subnet belonging to a larger network. Writer Bio
