Technitium DNS Server

Technitium DNS Server is a self-hosted DNS platform that can act as a recursive resolver (with caching) and as an authoritative DNS server for your own zones. It includes a web-based admin interface and security/privacy-focused DNS features such as encrypted DNS protocols and blocklists.

Key Features

• Recursive DNS resolver with caching for faster local name resolution
• Authoritative DNS hosting for zones with common record types and zone management
• DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) for encrypted client and forwarder traffic
• Built-in DNS-based blocking (ad/malware domain blocklists) with configurable allow/deny lists
• DNS forwarding/upstream configuration options (including encrypted upstreams)
• DHCP Server integration (optional) for LAN IP assignment and DNS configuration
• Web UI for configuration, logs, stats, and administration
• Extensible “Apps” system to add capabilities (plugin-like modules)

Use Cases

• Replace ISP/router DNS with a private LAN resolver supporting DoH/DoT
• Run internal authoritative DNS for homelab or small business domains
• Network-wide ad/malware domain blocking without client-side browser plugins

Limitations and Considerations

• Some advanced enterprise DNS features (e.g., anycast clustering) depend on external design/ops rather than being a single turnkey feature.

Technitium is a strong fit when you want an all-in-one DNS stack: recursive + authoritative, a web UI, encrypted DNS support, and optional DHCP and filtering features. It’s commonly deployed in homelabs and SMB networks as a Pi-hole/AdGuard Home alternative with deeper DNS server capabilities.
