[ipv6-ops] RE: [ipv6-ops] RFC 5952 converter tool

[Aaron Hughes]

Leo,

Fair enough.. Here's a quick script I just hacked together using the 5952 references:


> php foo.php 2001:db8:0:0:1:0:0:1
2001:DB8::1:0:0:1
> php foo.php 2001:0db8:0:0:1:0:0:1
2001:DB8::1:0:0:1
> php foo.php 2001:db8::1:0:0:1
2001:DB8::1:0:0:1
> php foo.php 2001:db8::0:1:0:0:1
2001:DB8::1:0:0:1
> php foo.php 2001:0db8::1:0:0:1
2001:DB8::1:0:0:1
> php foo.php 2001:db8:0:0:1::1
2001:DB8::1:0:0:1
> php foo.php 2001:db8:0000:0:1::1
2001:DB8::1:0:0:1
> php foo.php 2001:DB8:0:0:1::1
2001:DB8::1:0:0:1


> cat foo.php 
<?php

require "IPv6.php";

$ipaddress = $argv[1];

if(strstr($ipaddress,":" )) {
        $ipaddress = Net_IPv6::uncompress($ipaddress);
        $ipaddress = Net_IPv6::compress($ipaddress);
        $ipaddress = strtoupper($ipaddress);
        }

echo "$ipaddress\n";

?>

Using the pear module I just referenced:

* @category  Net
 * @package   Net_IPv6
 * @author    Alexander Merz <alexander.merz at web.de>
 * @copyright 2003-2005 The PHP Group
 * @license   http://www.opensource.org/licenses/bsd-license.php
 * @version   CVS: $Id: IPv6.php,v 1.18 2008/10/28 02:05:07 alexmerz Exp $
 * @link      http://pear.php.net/package/Net_IPv6

This should do what you are looking for reliably.

Cheers,
Aaron
