LanCalculator is capable of calculating subnet addresses and masks.

LanCalculator makes it possible to calculate the subnet addresses range and subnet masks quickly and broadcast address, net address, net prefix, and netmask inversion, which is used in the access control lists (ACL) of Cisco network equipment. One keypress is enough to calculate all parameters after entering a net address and mask.

LanCalculator provides you with full details on network configuration and calculates subnet parameters quickly. Once you enter the IP address and select one of the additional criteria (subnet prefix, number of subnet bits, the maximum number of subnets, or maximum number of hosts per subnet), LanCalculator will generate a list of all subnets with their parameters.

All the data provided by LanCalculator (including IP addresses, networks, subnets, and their IP addresses) can be easily copied to Clipboard or saved to a file.
