Hmm, Many thanks for your INPUT. Really profitable for me,
Here I TEST it with below code
#!/usr/bin/perl
use strict;
use warnings;
use Regexp::IPv4 qw($IPv4_re);
use Regexp::IPv6 qw($IPv6_re);
my $ipv4_address = "192.168.0.10";
my $ipv6_address = "2600:3c00::f03c:91ff:fedf:f016";
$ipv4_address =~ /^$IPv4_re$/ and print "IPv4 address\n";
$ipv6_address =~ /^$IPv6_re$/ and print "IPv6 address\n";
Hmm. It Works

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
