Oblivious DNS over HTTPS

Oblivious DNS is a privacy-friendly version of the DNS protocol. Preventing third-parties from keeping track of the sites you visit.

It builds on top of DoH (DNS over HTTPS) and adds a proxy server to prevent tracking. It was developed by Cloudflare, Apple and Fastly.

Currently, ODNS is not yet widely supported, but that could quickly change! Especially if Apple would push it to their iOS and macOS customers.
