Net::CIDR - Manipulate IPv4/IPv6 netblocks in CIDR notation

         use Net::CIDR;

           use Net::CIDR ':all';

           print join("\n",
                 Net::CIDR::range2cidr("192.68.0.0-192.68.255.255",
                                       "10.0.0.0-10.3.255.255"))
                      . "\n";
           #
           # Output from above:
           #
           # 192.68.0.0/16
           # 10.0.0.0/14

 Does anyone here has a script (or perl procedure) for converting range
of ips (i.e. 10.0.0.0 - 10.0.2.255) into cidr (i.e. result would be
10.0.0.0/23,10.0.2.0/24 from the example before). If not I'll do it, I'm
just hoping somebody is already done something this for another project...

Reply off the list.
