Usage

For best results, always select a server that is geographically close to you :-)

General

• DNS-over-HTTPS: Use https://servername.adfilter.net/dns-query
• DNS-over-TLS: Use tls://servername.adfilter.net:853

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.
• UNBOUND - Validating, recursive, caching DNS resolver.
• chrony - Contributing to the NTP Pool Project.
