This library has extensive test coverage using PHPUnit on PHP versions:7.1,7.2,7.3,7.4,8.0,8.1,8.2,8.3 and8.4.

Versions5.x.x of this library are compatible with PHP versions5.6 to8.3 (and will continue to receive bug fixes).

Versions6.x.x of this library are compatible with PHP versions7.1 andabove, and will receive continued support for future versions of PHP (alsoaccepting proposed new features).

Static analysis is performed with PHPStan atmax level on PHP8.4, usingcore, bleeding edge, and deprecation rules.

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

• There are three main classes:IPv4,IPv6, andMulti (for bothversion 4 and 6 addresses).
• Objects are created using a static factory methodIpInterface::factory() instead of the constructor tospeed up internal processes.
• When usingMulti, the default strategy for representing version 4 addressesinternally isIPv4-mapped.

<?phpdeclare(strict_types=1);useDarsyn\IP\Exception;useDarsyn\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($companyNetwork,25)) {thrownew \Exception('Request not from a known company IP address.');}// Is it coming from the local network?if (!$ip->isPrivateUse()) {record_visit($ip->getBinary(),$_SERVER['HTTP_USER_AGENT']);}
