iOS
On an iOS 14 or macOS Big Sur device you can download special ‘.mobileconfig’ file that adds DNS-over-HTTPS or DNS-over-TLS servers to the DNS settings. On each of the pages for a server I have a link to a .mobileconfig file for that server.
Android
Android 9 supports DNS-over-TLS natively. To configure it, go to Settings → Network & internet → Advanced → Private DNS and enter your domain name there.
Software
The servers providing the service are Ubuntu VMs running the following software.
- AGH - The front end for DOH/DOT/DOQ queries.
