DNS0.EU private DNS service shuts down over sustainability issues

Picus Blue Report 2025

The DNS0.EU non-profit public DNS service focused on European users announced its immediate shut down due to time and resource constraints.

Based in France, the service was built as a resilient infrastructure across several hosting providers in every member state of the European Union.

The team behindDNS0.EU replaced all content on the website with a short announcement informing that they discontinued the service.

“The dns0.eu service has been discontinued. We would have liked to keep it running, but it was not sustainable for us in terms of time and resources,” theDNS0.EU operator said.

Available alternatives

The team thanked infrastructure and security partners, and recommended that people switch to DNS4EU, a privacy-focused resolver developed by ENISA, or NextDNS, whose founders helped create DNS0.EU.

A DNS resolvertranslates the human-readable domain names into the numerical, machine-readableIP addresses so browsers can load the correct internet resources.

By default, connected devices usethe DNS service from the Internet Service Provider (ISP)but they can choose other options, like Cloudflare (1.1.1.1), Google (8.8.8.8), or OpenDNS (208.67.222.222).

DNS0.eu was a public recursive DNS resolver service launched in 2023 as a French-based non-profit organization. It promised no-logs functionality,end-to-end encryption for resistance to eavesdropping and tampering, as well as protection against malicious domains, be they phishing domains, or command-and-control (C2) malware servers.

It offered a free, secure, and GDPR-compliant DNS resolver that supportedDNS‑over‑HTTPS, DNS‑over‑TLS, DNS-over-QUIC, and DNS‑over‑HTTP/3. It operated 62 servers in 27 cities in all EU member states, boasting a median latency of 12 milliseconds.

In addition, DNS0.EU provided child safety-focused filters for adult content, piracy, and ads, as well as increased detection of potentially malicious domains by looking into typosquatting, domain parking patterns, TLD reputation, homograph domains, and DGA-created URLs.

DNS0.EU team’s recommendations for users,DNS4EU and NextDNS also include protection features against fraudulent and malicious content. However, NextDNS provides more granular filtering for websites and apps through privacy, security, and parental control options.

DNS4EU, co-funded by the European Union, is easier to set up and offers IP resolution that can block access towebsites with fraudulent or malicious content, protect against content that is explicit or inappropriate for children, and stop ads.

BleepingComputer has contacted DNS0.EU to learn more about the reasons behind the shut down of the service, and we will update this post when we hear back.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
