Formatters

Internally, this library uses the PHP functions inet_pton and inet_ntop. However the inet_ntop function formats some IP addresses in an inconsistent and non-standard way (for example, the IP address ::ffff:c22:384e would be returned as ::ffff:12.34.56.78 when converting its binary representation to human-readable protocol via inet_ntop).

This library provides a pure-PHP implementation called Darsyn\IP\Formatter\ConsistentFormatter to return IP addresses in the correct format, which is used by default.

However should you wish to use the native implementation for any reason, you may set the Darsyn\IP\Formatter\NativeFormatter globally:

<?php
use Darsyn\IP\Formatter\NativeFormatter;
use Darsyn\IP\Version\Multi as IP;

IP::setProtocolFormatter(new NativeFormatter);
$ip = IP::factory('::ffff:c22:384e');
$ip->getCompactedAddress(); // string("::ffff:12.34.56.78")
