use Regexp::IPv6 qw($IPv6_re);
$address =~ /^$IPv6_re$/ and print "IPv6 address\n";
DESCRIPTIONThis 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$/".
