Managing IP CIDR blocks

Galdor has asked for the wisdom of the Perl Monks concerning the following question:

Looking to manage hundreds of distinct subnets in separate Amazon AWS accounts and each will have unique VPC/CIDR subnets - The idea is to:

Ensure no overlaps of address blocks - each will have one or more and be unique
Be able to trace any IP address to it's relevant block - should need arise
Be economic with CIDR IP blocks - ie if they only need 10 IPs then pick a matching subnet mask

I though of writing a perl script to manage this - but not sure how to do it. Is this even possible? If so what modules do the wise monks propose?

As a satisfied customer of Net::CIDR::Lite I have no hesitation in recommending this module for most CIDR tasks. It should simplify some, if not all, of the actions you've outlined here.	[reply]
