adfree DNS

Public DNS over HTTPS (DoH) and DNS over TLS (DoT) resolver with ad, tracker, and malware filters.

We run a public privacy-protecting DNS server with advertising, tracker, and malware filtering. The Usable Privacy DNS (updns) service is accessible via the encrypted DoH and DoT protocols. We use the unified hosts from StevenBlack to filter unwanted domains.
