Greetings,

Why does the last test fail?

#!/usr/bin/perl

use Regexp::Common qw/ net number /;
use Test::More;
use strict;
use warnings;

my $valid_host = qr/\A

    (?: $RE{net}{IPv6} ) |
    (?: $RE{net}{IPv4} ) |
   (?: $RE{net}{domain}{-nospace}{-rfc1101}\.? )

\Z/x;

like('luna.example.com',        $valid_host, 'valid long hostname' );
like('luna',                    $valid_host, 'valid short hostname' );

like('fe80::42:5eff:feef:8f4f', $valid_host, 'valid ipv6 ip' );
like('10.0.0.1',                $valid_host, 'valid ipv4 ip' );

unlike('10.0 24',               $valid_host, 'invalid host or ip' );

done_testing;
