Если вы используете Perl try Net :: IPv6Addr

use Net::IPv6Addr;

if( defined Net::IPv6Addr::is_ipv6($ip_address) ){
  print "Looks like an ipv6 address\n";
}

NetAddr :: IP

use NetAddr::IP;

my $obj = NetAddr::IP->new6($ip_address);

Validate :: IP

use Validate::IP qw'is_ipv6';

if( is_ipv6($ip_address) ){
  print "Looks like an ipv6 address\n";
}
