Google Public DNS is a public recursive DNS resolver that users and organisations can configure as an alternative to their own or their provider's DNS service. It is available over classic DNS and over encrypted transports, DNS over HTTPS (DoH) and DNS over TLS (DoT). It is served worldwide through anycast routing, which sends each query to the nearest resolver. Google describes it as its own implementation of the DNS standards.
The service is operated by Google LLC, a subsidiary of Alphabet Inc. in the United States, and is covered by Google's general privacy policy. Google states that client IP addresses are kept only temporarily, in logs erased within 24 to 48 hours, and that permanent logs are anonymised to city or region level. Google does not state where its resolver servers are located, and neither the Public DNS pages nor the privacy page mention the GDPR or EU data residency. For European organisations, DNS queries are a sensitive data flow: the resolver is outside the EU, and no EU-specific processing commitment for this service was found.
