Nice tutorial...however it would be nice to add a routine that would also sort the ip addresses.

    Well, actually NetAddr::IP objects behave nicely when sorted, so this...

    sort @list_of_netaddr_ip_objects;

    ...Will do as expected. The trick is that the comparison operators used by sort and others, are overloaded too. The overload was done because I needed to sort addresses :)
