Technitium is a self-hosted, open-source DNS server that runs in Docker and offers a clean web interface, local DNS zones, ad blocking, forwarding, recursion, dynamic DNS updates via TSIG, DNS over HTTPS, and clustering. It positions itself as a middle ground between simple router DNS and complex solutions like BIND 9, while also replacing Pi-hole or AdGuard Home for network-wide ad blocking. The walkthrough covers Docker Compose deployment, creating primary DNS zones, adding A/PTR/CNAME records, configuring DHCP-based DNS distribution, enabling recursive resolution for privacy, setting up DNS blocklists, TSIG-based dynamic updates with Terraform, and DNS over HTTPS behind a Traefik reverse proxy.
