Immutable value object for IPv4 and IPv6 addresses, including helper methods and Doctrine support.

IP is an immutable value object for (both version 4 and 6) IP addresses. Several helper methods are provided for ranges, broadcast and network addresses, subnet masks, whether an IP is a certain type (defined by RFC's), etc.

This project aims for simplicity of use and any contribution towards that goal - whether a bug report, modifications to the codebase, or an improvement to the accuracy or readability of the documentation - are always welcome.

Code of Conduct

This project includes and adheres to the Contributor Covenant as a Code of Conduct.

Upgrading

This library is fairly similar to how it was in 3.3.1; the main differences are:

• There are three main classes instead of one: IPv4, IPv6, and Multi (for both version 4 and 6 addresses).
• Objects are created using a static factory method IpInterface::factory() instead of the constructor to speed up internal processes.
• A few methods have been renamed (see the API reference).
• Finally, the default for representing version 4 addresses internally has changed from IPv4-compatible to IPv4-mapped.

Brief Example

<?php

use Darsyn\IP\Exception;
use Darsyn\IP\Version\IPv4;

try {
    $ip = IPv4::factory('192.168.0.1');
} catch (Exception\InvalidIpAddressException $e) {
    exit('The IP address supplied is invalid!');
}

$companyNetwork = IPv4::factory('216.58.198.174');
if (!$ip->inRange($companyNetwork, 25)) {
    throw new \Exception('Request not from a known company IP address.');
}

// Is it coming from the local network?
if (!$ip->isPrivateUse()) {
    record_visit($ip->getBinary(), $_SERVER['HTTP_USER_AGENT']);
}
