DoH and DoT
A trial service
A&A run DNS over HTTPS (DoH) and DNS over TLS (DoT) resolves for customer use. There is information here: 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.

Help setting DoH or DoT on browsers and devices
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.
DoH is supported in Firefox's UI in version 69 and up.
- Scroll down to Network Setting...
- Scroll down and tick 'Enable DNS over HTTPS' and enter in a Custom provider: https://dns.aa.net.uk/dns-query
Checking your browser
In your Firefox URL bar, type:
about:networking 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.
DoH is expected to be a feature in Chrome version 78
DoT is supported in Android version 9 (Pie) and up
- Search for “DNS” in settings search bar
- Go to PrivateDNS setting screen
- Tap 'Private DNS provider hostname', and Set: dns.aa.net.uk
- Click Save
Using DOH with curl
Curl version 7.62.0 and above support using DoH for its DNS lookups. Here's an example:
curl --doh-url https://dns.aa.net.uk/dns-query https://www.aa.net.uk
This will download the www.aa.net.uk webpage and would have used the DOH server to resolve the DNS.
