A subnet is a shortened term for a sub-network. It is part of the internet Protocol, or IP services used in computer technology. It is an integral part of the system, and it has been around since even before the World Wide Web.

There are several reasons for subnetting:

  1. Isolate legacy protocols from the rest of the network
  2. Isolate packets for security purposes from the rest of the network
  3. To better troubleshoot network related problems, since the problem is usually related to a specific subnet

A subnet mask divides a network that uses the internet protocol (IP) addressing scheme into multiple subnetworks. An internet address has two parts: a network address and a host address.The network address defines group of members (hosts, computers, machines) in a network. The host address defines and actual host, computer, or machine that is a member of the network.
