Calc & Sort-IP - Sort and merge IP addresses and network blocks
More than once I’ve been confronted with a list of IP addresses that I wanted to sort, removing duplicates, merge into netblocks.
This calculator is designed to sort and merge multiple IP addresses/IP network blocks (consolidate adjacent and overlapping netblocks, remove duplicates, exclude another set of networks/IP's, sort the output).
A subnet mask and network/node calculator including IP address and mask conversion, CIDR mask (subnet mask), mask bits.
Results in dot-decimal and binary represantation.
