The Foundation for Applied Privacy operates a public DNS resolver that anyone can use free of charge. It supports DNS over HTTPS (DoH) and DNS over TLS (DoT) and performs DNSSEC validation. It does not filter or block anything: answers from the authoritative name servers are passed on unchanged. Plain DNS over UDP/53 is not offered, and DNS over QUIC is still on the operator's wishlist. You configure it with the DoH URL or DoT address in your operating system, browser or router.
The foundation is a non-profit organisation based in Vienna, Austria, and the DNS servers are in Vienna as well. There is no non-European parent company, and processing takes place inside the EU. The operator itself labels the DoH endpoint as experimental and best-effort, which matters for organisations considering production use. For details on data handling, the operator points to its own privacy policy, which you should read before relying on the service.
