=A trial service=
 
A&A run DNS over HTTPS (DoH) and DNS over TLS (DoT) resolvers for customer use. There is information here at [https://aa.net.uk/dns https://aa.net.uk/dns] which includes information on privacy and the terms and conditions.

As of September 2019, this is considered a 'trial' service, but is expected to continue and be an 'official' service for customers.
==Setting up DOH==
 
=A&A DNS Servers=
Menu -> Preferences -> Scroll down to Network Setting... -> Scroll down and tick 'Enable DNS over HTTPS' and enter in a Custom provider

Our privacy statement and terms can be found at: https://aa.net.uk/dns
 
=Testing if it’s working=
Firefox: in your URL bar, type: <code>about:networking#dns</code>
We have a testing domain, if you go to http://encrypted-dns-tester.aa.net.uk you will be directed to a page saying if your browser used DoT or DoH. The DNS lookup and page will fail if you are not using our DoT or DoH servers. (currently only over IPv6 and HTTP)
 
=Help setting DoH or DoT on browsers and devices=
==Checking the server with curl==
At the moment there is limited support for DoT and DoH on computers generally. Browsers are starting to support DoH, and Android from version 9 supports DoT. These are new protocols and it will take time before they are widely used.
 
==General resources==
Note: curl version 7.62.0 or above is required.

This will download the webpage but would have used the DOH server to resolve the DNS.
 
==Checking your browser==
 
In your Firefox URL bar, type: <code>about:networking</code> and enter. Then click DNS on the left, and you should see your DNS lookups, and they shoudl have TRR (Trusted Recursive Resolver) listed as true.

DoT is supported in Android version 9 (Pie) and up

Curl version 7.62.0 and above support using DoH for its DNS lookups. Here's an example:
 
curl --doh-url https://dohdns.aa.net.uk/dns-serverquery https://websitewww.aa.net.uk
 
This will download the www.aa.net.uk webpage butand would have used the DOH server to resolve the DNS.
