dunDNS is a private DNS resolver hosted in Europe. The service answers lookups for trusted destinations and withholds answers for ads, trackers, telemetry and known threats such as malware, phishing and command-and-control domains. You create a profile, choose blocklists and your own rules (allow, deny, rewrite), and use a unique address of the form your-id.dns.dundns.eu. It supports DNS over HTTPS, DNS over TLS, DNS over QUIC, Oblivious DoH and plain UDP/TCP. Devices can be tagged through the hostname or URL path, with separate profiles and family filters. Dashboards and a REST API are available.
The provider is DUNDNS LIMITED, a company in Dublin, Ireland, within the EU. According to the website, the servers run entirely in the EU and data is not exported; data centres are not named. Logging is off for new profiles; if you enable it, you can set retention from one hour to three months. The software is not open source. Third parties are involved in processing email and payments, such as Scaleway and Paddle.
