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.

Documentation

Full documentation is available in the docs/ folder.

Compatibility

This library has extensive test coverage using PHPUnit on PHP versions: 5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0, 8.1, 8.2, and 8.3.

Static analysis is performed with PHPStan at max level on PHP 8.3, using core, bleeding edge, and deprecation rules.

The Doctrine features for this library have been split off into their own package, darsyn/ip-doctrine.

Brief Example

  • There are three main classes: 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.
  • When using Multi, the default strategy for representing version 4 addresses internally is IPv4-mapped.
<?php declare(strict_types=1);

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']);
}
