DNS.SB: sovereignty score and 8 European alternatives

DNS.SB is a free DNS resolver that emphasises speed, privacy and encryption. It supports DNS over HTTPS and DNS over TLS and offers short, easy-to-remember IPv4 and IPv6 addresses, including anycast endpoints and endpoints for individual locations. The operator states that DNSSEC is enabled and that nothing is logged ("no logs, forever"); its privacy policy says DNS queries, the associated IP addresses and timestamps are not recorded. The service runs on xTom's global anycast network.

The operator is xTom GmbH in Düsseldorf, Germany, and so falls under European law. The servers, however, are spread over several continents: the documentation lists locations such as Frankfurt, Amsterdam and London, but also sites in North America and Asia, and each query is answered by the nearest server. The DNS.SB website and documentation are published as open source (MIT); the resolver software itself is not described as open source in the sources consulted. A European organisation that wants DNS traffic to stay within the EU cannot enforce that with this service.

Why digital sovereignty matters with DNS.SB

DNS.SB is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

DNS.SB hosts data in EU, US, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

DNS.SB is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs DNS.SB together with your other vendors and gives a total score, a heatmap and the main risk drivers.
