in reply to Validate Ip address Regexp

Regexp::Common already has a regex for you. Don't stress building your own. 

   use Regexp::Common qw/ net number /;

   # these become available:
   # $RE{net}{IPv6}
   # $RE{net}{IPv4}

   if ( $ip =~ m/$RE{net}{IPv4}/ ){
      print 'match!'
   }

    Don't stress building your own.

    ... except as an exercise for building your familiarity with and confidence in regex construction.
