Technitium DNS Server

Self-host a powerful open-source DNS server. Block ads and malware network-wide and encrypt DNS traffic for enhanced privacy and security on any OS.

Take control of your internet experience by self-hosting your own DNS server. Standard DNS resolvers can expose your browsing habits to your ISP, but with a local server, you can mitigate tracking and enhance your network's privacy. It works out-of-the-box with minimal configuration and provides a user-friendly web console for easy management.

This server allows you to block ads and malware for your entire network using customizable block lists. It improves performance by caching frequent queries, making websites load faster. For maximum security, it supports encrypted protocols like DNS-over-TLS, DNS-over-HTTPS, and DNS-over-QUIC, protecting your traffic from snooping and man-in-the-middle attacks.

Key features include:

  • Cross-platform support for Windows, Linux, macOS, and Raspberry Pi.
  • Docker image for easy deployment.
  • Functions as both an authoritative and recursive DNS server.
  • Advanced caching with prefetching and persistent cache options.
  • DNSSEC validation for authenticating DNS responses.
  • Built-in DHCP server for network management.
  • Clustering feature to manage multiple server instances.
