UncensoredDNS, also known by its Danish name Censurfridns, is a free public DNS resolver service open to anyone. It consists of two servers, an anycast service and a unicast service. Queries are expected to be encrypted: DNS-over-TLS and DNS-over-HTTPS are available, and since October 2025 the service also supports DNS-over-QUIC and DNS-over-HTTP/3. The project dates from 2009 and presents itself as an alternative to the filtered resolvers that Danish internet providers must run. It is delivered as a service: you configure your device or network to use its addresses.
UncensoredDNS is run from Denmark by Thomas Steen Rasmussen, a private individual, at his own expense; no company or parent organisation stands behind it. The unicast server is hosted on AS9167 in Copenhagen, and the anycast addresses are announced from several locations that the project does not list. The project's main pages do not describe a logging policy, so organisations with compliance requirements should ask the operator before relying on the service.
