Pseudo IPv4
===========

[](#pseudo-ipv4)

[![Build Status](https://camo.githubusercontent.com/3ab994e1dfd20430b1dd0f37e5eb3442a1304d0d948d2c1ee4e1a68f487ceb2b/68747470733a2f2f7472617669732d63692e6f72672f6f7373696e6b696e652f70736575646f2d697076342e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/ossinkine/pseudo-ipv4)

Pseudo IPv4 is a library which converts IPv6 address to IPv4 in Class E space (240.0.0.0 - 255.255.255.255). It can be helpful if your app operates with IPv4 only but the customer uses IPv6. For more information see [CloudFlare solution](https://blog.cloudflare.com/eliminating-the-last-reasons-to-not-enable-ipv6/)

How it works
------------

[](#how-it-works)

Pseudo IPv4 determines if given address is 6to4 and gets original IPv4. Otherwise it gets 8 first bytes from given IPv6 address and converts them to 4 bytes.

Installation
------------

[](#installation)

```
composer require ossinkine/pseudo-ipv4
```

Usage
-----

[](#usage)

Create a converter instance and pass an IPv6 address into it.

```
use Ossinkine\PseudoIpv4\PseudoIpv4Converter;

$ipv6 = '2001:0db8:11a3:09d7:1f34:8a2e:07a0:765d';
$converter = new PseudoIpv4Converter();
$ipv4 = $converter->convert($ipv6);
```

If you unsure the address is IPv6 you can catch an appropriate exception.

```
use Ossinkine\PseudoIpv4\Exception\WrongIpv6Exception;
use Ossinkine\PseudoIpv4\PseudoIpv4Converter;

$ip = $_SERVER['REMOTE_ADDR'];
$converter = new PseudoIpv4Converter();
try {
    $ipv4 = $converter->convert($ip);
} catch (WrongIpv6Exception $exception) {
    $ipv4 = $ip;
}
```
