The Laravel framework is open-sourced software licensed under the MIT license

Much of this library borrowed heavily from ReactPHP/DNS

Installation

The service provider should automatically register itself under Laravel. If not, you can manually add Smorken\Dns\ServiceProvider::class to the providers section of config/app.php.

Publish the config (under Laravel):

$ php artisan vendor:publish --provider="Smorken\Dns\ServiceProvider"

Notes

This is a synchronous dns client (purposefully, for my use case).

I created this for reverse (PTR) lookups. I added A record lookups as part of testing, but that is as far as I made it. Further types can be added - feel free to create a pull request if you use it and want more types handled.

Laravel

$query = App::make(\Smorken\Dns\Contracts\Query::class);
$message = $query->query('8.8.4.4', \Smorken\Dns\Contracts\Models\Message::TYPE_PTR);
$hostname = $message->answers[0]->data;

Manual use

Factory

// defaults
$message = \Smorken\Dns\Factory::query('8.8.4.4', \Smorken\Dns\Contracts\Models\Message::TYPE_PTR);
$hostname = $message->answers[0]->data;
// override query
$transports = [
    new \Smorken\Dns\Transports\Udp('8.8.8.8', 0.5),
    new \Smorken\Dns\Transports\Tcp('8.8.8.8', 0.5),
];
$h = new \Smorken\Dns\Handler(new \Smorken\Dns\Pointer()/*, Model[], Parser[], Label[]*/);
$query = new \Smorken\Dns\Query($h, $transports);
\Smorken\Dns\Factory::$query = $query;
$message = \Smorken\Dns\Factory::query('8.8.4.4', \Smorken\Dns\Contracts\Models\Message::TYPE_PTR);
$hostname = $message->answers[0]->data;

Query

$transports = [
    new \Smorken\Dns\Transports\Udp('8.8.8.8', 0.5),
    new \Smorken\Dns\Transports\Tcp('8.8.8.8', 0.5),
];
$h = new \Smorken\Dns\Handler(new \Smorken\Dns\Pointer());
$query = new \Smorken\Dns\Query($h, $transports);
$message = $query->query('8.8.4.4', \Smorken\Dns\Contracts\Models\Message::TYPE_PTR);
$hostname = $message->answers[0]->data;

Handler

$handler = new \Smorken\Dns\Handler(new \Smorken\Dns\Pointer());
$t = new \Smorken\Dns\Transports\Udp('8.8.8.8');
$question_message = $handler->newQuery('8.8.4.4.', \Smorken\Dns\Contracts\Models\Message::TYPE_PTR);
$packet = $handler->toBinary($question_message);
$response = $t->send($packet);
$answer_message = $handler->fromBinary($response);
$hostname = $answer_message->answers[0]->data;
