What Technitium DNS Server actually does

Technitium DNS Server is an authoritative and recursive Domain Name System server that includes built-in ad blocking capabilities. It allows you to host your own DNS infrastructure and resolve network queries locally while filtering unwanted domains. The application is written in C# and is distributed under the GPL-3.0 licence.

Best fit: Self-hosters who want fine-grained control over their local network's DNS resolution and require an integrated ad-blocking solution without managing a separate DNS sinkhole.

Worth knowing: Running your own recursive and authoritative DNS server introduces operational complexity if misconfigured, as network-wide internet access depends on its uptime and correct setup.

Deployment notes

Deployment is typically handled via Docker containers, requiring persistent storage for configuration data and logs. You will need to ensure port 53 is correctly mapped and avoid conflicts with host-level DNS resolvers.
