A trial service

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.

FireFox

DoH is supported in Firefox's UI in version 69 and up.

Menu
Preferences
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.

Chrome

DoH is expected to be a feature in Chrome version 78

Android (DoT)

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

Settings
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.
