The DNS0.EU non-profit public DNS resolver, which focused on European users and was based in France, has been shut down immediately because the operator said it was not sustainable in terms of time and resources. The project replaced its website content with a brief announcement that the service had been discontinued.
The service was built as a resilient infrastructure across several hosting providers in every European Union member state and, at the time it operated, ran 62 servers in 27 cities with a reported median latency of 12 milliseconds. DNS0.EU, launched in 2023, offered no-logs operation and end-to-end encryption to resist eavesdropping and tampering; the launch was publicized on social media.
DNS0.EU supported DNS-over-HTTPS, DNS-over-TLS, DNS-over-QUIC and DNS-over-HTTP/3 and provided protection against malicious domains, including phishing and command-and-control infrastructure. It also included content filters targeting adult content, piracy and ads, and used signals such as typosquatting, domain parking patterns, top-level domain reputation, homograph domains and DGA-generated URLs to detect potentially harmful sites.
The DNS0.EU team thanked infrastructure and security partners and recommended users switch to alternative resolvers including DNS4EU, a privacy-focused resolver developed with European Union support, or NextDNS, whose founders helped create DNS0.EU. The team noted that NextDNS offers more granular filtering options while DNS4EU is easier to set up and provides IP resolution that can block access to fraudulent or malicious content.
A DNS resolver translates human-readable domain names into machine-readable IP addresses so browsers and other clients can load internet resources. Devices typically use the DNS service supplied by their internet service provider by default but can be configured to use public resolvers such as Cloudflare (1.1.1.1), Google (8.8.8.8) or OpenDNS (208.67.222.222).
The public announcement did not provide additional details about timing, staffing or whether any parts of the infrastructure will be preserved.
