DoH (DNS over HTTPS) PHP Client
This is a proof of concept for a DoH (DNS over HTTPS) client in PHP. It is based on the latest draft
https://tools.ietf.org/html/draft-ietf-doh-dns-over-https-03 and supports the GET method with the DNS UDP wire format. This is a work in progress and only the A, AAAA and CNAME records are supported.
MX and NS are coming soon.
It supports CloudFlare's , Google's and CleanBrowsing DoH servers.
This tool should be executed from the command line and it has a similar output as the
host command. Example:
$ php doh-php-client.php Usage: doh-php-client.php [server:cloudflare,google,cleanbrowsing] [domain.com] <type: A, AAAA or CNAME> $php doh-php-client.php cloudflare github.com github.com has address 184.108.40.206 github.com has address 220.127.116.11
Or for IPv6:
$ php doh-php-client.php google sucuri.net AAAA sucuri.net has IPv6 address 2a02:fe80:1010::16
You have to specify as the first argument which DoH server to use. We support "google", "cloudflare" or "cleanbrowsing".
This is just an initial test version. We will be spliting it into a better organized package later.
