This script is a fork of ipcalc (0.41). It's basically the same program but with a lot of small improvements to the output (and a huge amount of cleaning under the hood).
The program takes an IP address and netmask and calculates the resulting network address, wildcard mask, broadcast address and host range. By specifying a second netmask you can design subnets and supernetworks.
It's really easy to use ipkalk. Run the script for example usage.
You need to have Perl installed to run this.
The basic functionality is all there but there is a lot of small issues with the script so if you know Perl and want to help out please take a look at the TODO file (or just check the source file for errors). If you don't mind reinventing the wheel then a complete rewrite might be in order.
I don't plan on doing much more work with this script since i don't know Perl.
