Every IP Address has a couple of components to it, the network and host address. The piece that separates the IP Address into the multiple pieces is called the Subnet Mask. Sub-netting the IP Address divides the host piece of an IP Address into a subnet and host address. Use the provided Subnet Mask Calculator to retrieve sub-network information from the IP Address and Subnet Mask. Commonly used netmask’s for classed networks are Class A, Class B, and Class C. The Subnet Calculator is used to divide an IP network into subnetworks by calculating network address, subnet mask, broadcast address and host IP address range
