What is a subnet and why do I need a subnet Calculator?

A subnet (short for "subnetwork") is an identifiable part of an organizations IP network. Often, a subnet may represent all the machines at one geographic location, in one building, or the same virtual local area network (VLAN). Having an organizations network divided into subnets allows it to be connected to the Internet with a single shared network address. Without subnets, an organization could get multiple connections to the Internet, one for each of its physically separate subnetworks, but this would require an unnecessary use of the limited number of network numbers the Internet has to assign.

This Subnet calculator is used by network engineers to calculate subnet masks, number ranges of useable IP addresses, broadcast ip addresses and network numbers.
