Historical Supernet Network Calculator
The IP Supernet Calculator enables Supernet network calculations using network class, IP address, subnet mask, mask bits, maximum required IP addresses and maximum required supernets.
Results of the supernet calculation provide the wildcard mask, for use with ACL (Access Control Lists), supernet route (supernet network address) and the supernet address range for the resulting supernet network.
For classless supernetting, please use the CIDR Calculator. For classful subnetting, please use the IP Subnet Calculator. For simple ACL (Access Control List) wildcard mask calculations, please use the ACL Wildcard Mask Calculator.
