Technitium DNS Server

Technitium DNS Server Overview

Technitium DNS Server is an open-source, self-hosted authoritative/recursive DNS server that offers ad-blocking functionality. This project enables users to take control of their domain name system (DNS) infrastructure and enjoy the benefits of privacy, security, and customization. By hosting your own DNS server, you can block unwanted advertisements, encrypt DNS queries using DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), or DNS-over-QUIC (DoQ), and maintain a high level of control over your network's DNS traffic.

Main Features

1. Authoritative/Recursive DNS Server: Technitium DNS Server is designed to work as both an authoritative and recursive DNS server, allowing it to handle DNS queries for local domains and forward unresolved queries to upstream recursive resolvers.
2. Ad-Blocking: The project includes a built-in ad-blocking feature that uses DNS sinkholes to redirect traffic away from known ad servers.
3. DNS-over-HTTPS (DoH): Technitium DNS Server supports encryption of DNS queries using DoH, which helps protect user privacy and prevent eavesdropping.
4. DNS-over-TLS (DoT): The project also enables encryption of DNS queries using DoT, providing an additional layer of security for users.
5. Cross-Platform: Technitium DNS Server is developed in C# and can be run on various platforms, including Windows, Linux, and macOS.
6. Custom Properties: Users can customize the server's behavior by modifying configuration files or setting custom properties through a simple GUI interface.
7. GPLv3.0 License: The project is released under the GNU General Public License version 3.0 (GPLv3.0), ensuring that users have the freedom to modify and distribute the code as needed.

Overall, Technitium DNS Server offers a powerful and flexible solution for anyone looking to take control of their DNS infrastructure and enjoy enhanced security, privacy, and customization options.
