Laravel DNS

A DNS service and facade for Laravel. Includes configurable 'doh' and 'system' drivers or create your own driver.

Driver	Description
doh	DNS over HTTPS (DoH)
system	PHP's dns_get_record()

Installation

Install the package via composer:

composer require jinomial/laravel-dns

The default configuration is DoH through Cloudflare with Guzzle defaults:

'doh' => [
    'driver' => 'doh',
    'endpoint' => env('DOH_ENDPOINT', 'https://cloudflare-dns.com/dns-query'),
    'guzzle' => [
        'connect_timeout' => 0,
        'timeout' => 0,
        'verify' => true,
    ]
],

Publish the config file to make changes to the configuration:

php artisan vendor:publish --provider="Jinomial\LaravelDns\DnsServiceProvider" --tag="laravel-dns-config"

Usage

Query for a AAAA record using the default driver:

$response = Dns::query('ipv6.localhost.jinomial.com', 'aaaa');
print_r($response);

// > Response varies by driver

Use a specific driver:

$response = Dns::socket('system')->query('ipv4.localhost.jinomial.com', 'a');

doh driver responses

The doh driver uses Cloudflare's DNS over HTTPs with JSON for lookups.

See the response documentation for details about the response format.

Array

    [RA] => 1
    [AD] =>

        (
            [0] => Array
                (
                    [name] => ipv6.localhost.jinomial.com
                    [type] => 28
                )

        )

    [Answer] => Array
        (
            [0] => Array
                (
                    [name] => ipv6.localhost.jinomial.com
                    [type] => 28
                    [TTL] => 298
                    [data] => ::1
                )

        )

)

system driver responses

The system driver uses PHP's dns_get_record method for lookups.

See the dns_get_record documentation for details about the response format.

Array
(
    [0] => Array
        (
            [host] => ipv6.localhost.jinomial.com
            [class] => IN
            [ttl] => 377
            [type] => AAAA
            [ipv6] => ::1
        )

)

Batch Queries

Multiple lookups can be performed at once.

$response = Dns::query([
    [
        'name' => 'ipv6.localhost.jinomial.com',
        'type' => 'AAAA',
    ],
    [
        'name' => 'ipv4.localhost.jinomial.com',
        'type' => 'A',
    ],
]);

The doh driver supports asynchronous queries.

$promises = Dns::query($queries, null, ['async' => true]);
$response = Dns::unwrap($promises);

Custom Drivers

Create a class that extends Jinomial\LaravelDns\Sockets\Socket.

Implement public function query() according to the Jinomial\LaravelDns\Contracts\Dns\Socket contract.

Register a driver factory with the Jinomial\LaravelDns\DnsManager.

    /**
     * Application service provider bootstrap for package services.
     *
     * \App\Dns\Sockets\DnsResolver is my custom driver class I made.
     * The DnsManager needs to know how to construct it.
     */
    public function boot(): void
    {
        $dnsLoader = $this->app->get(\Jinomial\LaravelDns\DnsManager::class);
        $driverName = 'my-custom-driver';
        $dnsLoader->extend($driverName, function () use ($driverName) {
            return new \App\Dns\Sockets\DnsResolver($driverName);
        });
    }

Testing

Run all tests:

composer test

Test suites are separated into "unit" and "integration". Run each suite:

composer test:unit
composer test:integration

Tests are grouped into the following groups:

• network
• drivers
• doh
• system
• manager
• facades
• commands

Run tests for groups:

composer test -- --include=manager,facades

Network tests make remote calls that can take time or fail. Exclude them:

composer test:unit -- --exclude=network
