Technitium DNS Server

Technitium DNS Server is an open-source, cross-platform DNS server that can run as both an authoritative server for your zones and a recursive resolver for clients on your network. It includes a browser-based administration console and can improve privacy, performance, and control by handling DNS locally and supporting encrypted upstream DNS.

Key Features

• Authoritative and recursive DNS operation, including forwarding and conditional forwarding
• Encrypted DNS services and forwarders: DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC (including HTTP/1.1, HTTP/2, and HTTP/3 for DoH)
• DNSSEC validation and signed-zone support, plus advanced record types and zone features
• DNS-based blocking (ads/malware) via block lists, with options like regex-based and per-client/subnet policies (via DNS Apps)
• Web-based admin console with multi-user, role-based access, API tokens, and optional TOTP 2FA
• Built-in DHCP server for multiple networks and IPv6 support
• Query logging, system logging, statistics, caching features (including persistent cache) and clustering for managing multiple instances

Use Cases

• Home or small-office DNS resolver with network-wide ad/malware blocking and encrypted upstream DNS
• Self-hosted authoritative DNS for internal zones and lab environments with zone transfers and DNSSEC
• Network visibility and control through query logs, policy routing, and split-horizon responses

Limitations and Considerations

• Default web console credentials and auto-login behavior require immediate hardening after installation
• Some advanced behavior is implemented through DNS Apps, which may add operational complexity compared to basic DNS setups

Technitium DNS Server is well-suited for users who want a powerful DNS platform that combines authoritative hosting, recursive resolution, privacy-focused encrypted DNS, and centralized web-based management. It can serve as a Pi-hole alternative while also covering advanced DNS features typically found in dedicated DNS infrastructure.
