Network Calculator for IPv4 and IPv6 Addresses

To calculate the network parameters, specify the IP address and select the mask from the ready list. The following parameters will be calculated: network mask, network mask inversion (Wildcard mask, used in Cisco network equipment), network address, broadcast address, first and last hosts (Hostmin and Hostmax) and the total number of hosts.

All parameters will be presented in 3 formats: decimal, hexadecimal and binary. Thus, our ip subnet calculator can also be used as a converter, for example, to convert ip addresses from decimal to binary format.
