LanCalculator

LanCalculator is the easiest and most convenient tool to analyze and calculate IPv4/IPv6 networks.

IP Subnet Calculator for IPv4/IPv6 Networks

Running and monitoring large networks can be time-consuming and tedious. One great workaround is to split a large network into smaller subnets; but this makes it difficult to design and calculate each subnet properly.

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, 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.
