Re: subnet aggregation script

Does anyone know of a tool/script that can aggregate subnets feed to it via command line? Meaning if I give it multiple /30s (or any size subnet) it will scrunch them together.

Here is a Perl script to do just that. My normal one reads from STDIN. #!/usr/bin/perl use Net::CIDR::Lite; my $cidr = Net::CIDR::Lite->new (); foreach (@ARGV) { if (/^[0-9a-f\.:]+(\/\d+)?$/) { $cidr->add_any ($_); } } print (join ("\n", $cidr->list ()));
