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. =Help with browsers and devices=▼ ==FireFox==▼ =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▼ [[File:Firefox-DoH.png\|thumb]]▼ {\| class="wikitable" !
