I wrote the code below some time ago. I've not used it

Not Perl, though this may be useful depending on your environment:
https://github.com/rus-cert/compress-cidr
The examples are for IPv6, though I use it to consolidate lists of IPv4 in a
variety of jobs/scripts without issue. YMMV.

The Perl Net::Netmask module is also worth checking out. It may not be
better at aggregation but it does have other functions that could be
helpful. I use the shortest match address lookup functions of Net::Netmask
very heavily and have reproduced them in a R / C++ package.
