       This module exports the $IPv6_re regular expression that matches any valid IPv6 address as described in
       "RFC 2373 - 2.2 Text Representation of Addresses" but "::". Any string not compliant with such RFC will
       be rejected.

       To match full strings use "/^$IPv6_re$/".

         use Regexp::IPv6 qw($IPv6_re);

         $address =~ /^$IPv6_re$/ and print "IPv6 address\n";
