=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.
=A&A DNS Servers=

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)
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==
DoH is supported in Firefox's UI in version 69 and up.
#Menu
#Preferences
==Chrome==
DoH is expected to be a feature in Chrome version 78 or 79.
https://blog.chromium.org/2019/09/experimenting-with-same-provider-dns.html
==Android (DoT)==
DoT is supported in Android version 9 (Pie) and up

==Stubby==
[https://dnsprivacy.org/wiki/display/DP/DNS+Privacy+Daemon+-+Stubby Stubby] is an application acts as a local DNS resolver on port 53 but does its lookups over TLS (DoT) which means it can act as a DNS proxy for your whole machine.
Adding our servers should be enough:
- address_data: 2001:8b0::2022
tls_auth_name: "dns.aa.net.uk"
- address_data: 2001:8b0::2023
tls_auth_name: "dns.aa.net.uk"
- address_data: 217.169.20.22
tls_auth_name: "dns.aa.net.uk"
- address_data: 217.169.20.23
tls_auth_name: "dns.aa.net.uk"
And once running, test with
dig +short @::1 encrypted-dns-tester.aa.net.uk
81.187.39.93
If encrypted-dns-tester.aa.net.uk resolves to 81.187.30.81 then it wasn't using our DoT servers.
==Using DOH with curl==
curl --doh-url https://dns.aa.net.uk/dns-query https://www.aa.net.uk
This will download the www.aa.net.uk webpage
