PHP DNS Server

This is an Authoritative DNS Server written in pure PHP. It will listen to DNS request on the default port (Default: port 53) and give answers about any donamin that it has DNS records for. This class can be used to give DNS responses dynamically based on your pre-existing PHP code.

Support Record Types

• A
• NS
• CNAME
• SOA
• PTR
• MX
• TXT
• AAAA
• OPT
• AXFR
• ANY

PHP Requirements

• PHP 5.3+
• Needs either sockets or socket_create PHP extension loaded (which they are by default)

Example:

Here is an example of some DNS records

<?php

require "vendor/autoload.php";

// JSON formatted DNS records file
$record_file = 'dns_record.json';
$jsonStorageProvider = new yswery\DNS\JsonStorageProvider($record_file);

// Recursive provider acting as a fallback to the JsonStorageProvider
$recursiveProvider = new yswery\DNS\RecursiveProvider($options);

$stackableResolver = new yswery\DNS\StackableResolver(array($jsonStorageProvider, $recursiveProvider));

// Creating a new instance of our class
$dns = new yswery\DNS\Server($stackableResolver);

// Starting our DNS server
$dns->start();

And Here is us querying it and seeing the response

$ dig @127.0.0.1 test.com A +short
111.111.111.111

$ dig @127.0.0.1 test.com TXT +short
"Some text."

$ dig @127.0.0.1 test2.com A +short
111.111.111.111
112.112.112.112
