README

This package contains a class that can fetch DNS records. Its an extended version of Spatie\DNS as they want to keep their version minimal.

use Ante\DnsParser\Dns;

$dns = new Dns();

$dns->getRecords('spatie.be'); // returns all available dns records

$dns->getRecords('spatie.be', 'A'); // returns only A records

You can use various methods to retrieve info of a record.

$records = $dns->getRecords('spatie.be')

$hostNameOfFirstRecord = $records[0]->host();

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Installation

If you do not have dig installed you will need it.

You can install the package via composer:

composer require spatie/dns

Usage

The class can get these record types: A, AAAA, CNAME, NS, PTR, SOA, MX, SRV, TXT, DNSKEY, CAA, NAPTR.

use Ante\DnsParser\Dns;

$dns = new Dns();

$dns->getRecords('spatie.be'); // returns all available dns records

$dns->getRecords('spatie.be', 'A'); // returns only A records
$dns->getRecords('spatie.be', ['A', 'CNAME']); // returns both A and CNAME records
$dns->getRecords('spatie.be', DNS_MX); // returns only MX records
$dns->getRecords('spatie.be', DNS_A | DNS_AAAA); // returns both A and AAAA records

getRecords will return an array with objects that implement the Ante\DnsParser\Records\Record interface.

Working with DNS records

Here's how you can fetch the first A-record of a domain.

$ARecord = $dns->getRecords('spatie.be', 'A')[0];

These methods can be called on all records:

host(): returns the host (spatie.be)
ttl(): return the time to live (900)
class(): returns the class (IN)
type(): returns the type (A)

When converting a record to a string you'll get a string with all info separated with tabs.

(string)$ARecord // returns `spatie.be.              900     IN      A       138.197.187.74`

Some records have additional methods available. For example, records of type A have an additional ip() method. To know which extra methods there are, check the docblocks above all record classes in the source code.

Using a specific nameserver

You can get records from a specific nameserver.

use Ante\DnsParser\Dns;

(new Dns)
    ->useNameserver('ns1.openminds.be') // use ns1.openminds.be
    ->getRecords('spatie.be');

Guessing a record

When you have a string that contains a dns record, you can convert it to a Record

use \Ante\DnsParser\Support\Factory();

// returns instance of \Ante\DnsParser\Records\CNAME
(new Factory())->guess('www.spatie.be.       300     IN      CNAME   spatie.be.');

Using custom handlers

A Handler is responsible for fetching DNS records of a certain type.

By default, these handlers that ship with the package are used:

Ante\DnsParser\Handler\Dig
Ante\DnsParser\Handler\DnsGetRecord

You can create custom handlers. A valid handler is any class that extends from Ante\DnsParser\Handler\Handler.

A custom handler class can be used by passing it to useHandlers on Ante\DnsParser\Dns.

$results = $this->dns
    ->useHandlers([new YourCustomHandler()])
    ->getRecords('spatie.be');

Under the hood

We will use dig to fetch DNS info. If it is not installed on your system, we'll call the native dns_get_record() function.
