There are few tools to deal with ip addresses, you can study the code : python: IPy https://github.com/haypo/python-ipy perl : ipcalc: /usr/ports/net-mgmt/ipcalc ... Basically, an ip address is just a number. IPy associates also a prefix length in an "IP" object. So it can represent a host or a network which is nice.
