Re: Splitting IP ranges depending on overlap conditions

I'm not aware of a CPAN module that can do this.

You could convert your dotted-quad IP-addresses to integers, so you can do some simple math with them:

if ( $ip =~ /^(\d+)\.(\d+)\.(\d+)\.(\d+)$/ ) {
  $number = $1 >> 24 + $2 >> 16 + $3 >> 8 + $4
}
