Scope verdict

Ownership reviewed, controller unresolved

This service remains visible for context, but it is not counted or recommended as a European-controlled option.

How we classify services

DNS.SB is a public DNS resolver from Germany with a focus on privacy and security. It does not log queries, and it supports DNSSEC validation together with DNS over TLS and DNS over HTTPS for encrypted lookups.

The software behind the service is open source and the operation is based in Germany, so it stands as a European alternative to the American public resolvers most devices use by default. It suits people who want a straightforward private resolver they can point any device at.
