Technitium DNS Server<\/strong> is an open-source DNS solution that combines recursive and authoritative resolvers [Link<\/a>].<\/p>\n

Besides the extensions\/plugins, Technitium is a monolithic (C#) application with an integrated web GUI (that is the biggest difference when compared with PowerDNS<\/strong>).<\/p>\n

In previous posts, I introduced the whole PowerDNS<\/strong> stack [Link<\/a>] and different design strategies for geographic resilience [Link<\/a>].<\/p>\n

The purpose of this post is to introduce Technitium<\/strong> as a powerful, all-in-one DNS solution. It is not as mature as BIND, Unbound, DNSMasq, or even PowerDNS, but it arguably fills the gaps of all of them in a single package.<\/p>\n

Another highlight will be the resilient design built around the resolvers, using the “hidden primary” concept proposed in NIST SP 800-81r3 – Secure Domain Name System (DNS) Deployment Guide<\/strong> [Link<\/a>].<\/p>\n
