Re: Unsorted IP Addr list to sorted IP list with ranges (CPAN module candidates)by ybiC (Prior)

I've never gotten around to doing this programaticaly, but I suspect that one of the following modules (or a combination) might maybe do what you're looking for. I've sorted the following list with what looks to be more promising modules first:
striving toward Perl Adept
(it's pronounced "why-bick")
Update: Fwiw, I found these modules through http://search.cpan.org using these terms: netmask, subnet, ip address, and cidr.
Update II: Anonymonk provides below what was beginning to percolate into my brain - that is, convert the dotted quad addresses to their (real) binary values, then sort and look for sequential blocks. ++anonymonk.
