WHAT IS IT?
Technitium DNS Server is an open source, self-hosted DNS server that is both authoritative and recursive. You drop it on your network in place of your ISP's DNS to resolve queries locally, block ads and malware at the DNS level, and encrypt your traffic. It is managed entirely from a web console, with no hand-editing of zone files.
WHY IS IT INTERESTING?
- Authoritative and recursive: host your own zones and resolve everything else from the same server.
- Native encrypted DNS: DNS-over-TLS, DNS-over-HTTPS and DNS-over-QUIC, as client and server, to stop surveillance and content injection.
- Ad/malware blocking: blocklist management with CNAME cloaking, Pi-hole style but built in.
- Advanced caching: persistent cache, prefetching and stale-serve to hold load (100,000+ req/s claimed).
- DNSSEC, DHCP and clustering: RSA/ECDSA/EdDSA signing, a built-in DHCP server and multi-instance management from one console.
USE CASES
- Block ads and trackers across an entire home network.
- Host authoritative DNS for your own domains.
- Encrypt DNS queries to escape ISP filtering and snooping.
- Run split-horizon or geolocation-based responses on a corporate network.
