=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.

Our privacy statement and terms can be found at: https://aa.net.uk/dns
=Testing if it’s working=
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)
==Checking the DOH 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==
* [https://support.mozilla.org/en-US/kb/firefox-dns-over-https FireFox's DoH info]
*[https://www.chromium.org/developers/dns-over-https Chromium's DoH developer info]
▲==FireFox==
curl --doh-url https://doh-server https://website▼
DoH is supported in Firefox's UI in version 69 and up.
#Menu

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