## What it is
Technitium DNS Server is an open-source, cross-platform authoritative and recursive DNS server built on .NET, designed for self-hosting with a web-based management console. It supports encrypted DNS protocols (DNS-over-TLS, DNS-over-HTTPS, DNS-over-QUIC, DNS-over-TOR), includes a built-in DHCP server, and enables network-wide ad and malware blocking.

## Use cases
- self-host a DNS server for privacy and security
- block ads and malware at the DNS level for an entire network
- encrypt DNS traffic using DNS-over-HTTPS, DNS-over-TLS, or DNS-over-QUIC
- run an authoritative DNS server for my own domains
- cache DNS queries to speed up web browsing
- view DNS logs and stats to understand network activity
- run a DHCP server alongside DNS on a home network
- bypass ISP DNS monitoring and content injection

## When to choose
- you want a self-hosted DNS server with an easy web console and minimal setup
- you need network-wide ad/malware blocking with encrypted upstream DNS
- you need both authoritative and recursive DNS plus DHCP in one cross-platform tool
- you want DNS-level logging and stats for your home or organization network

## When to avoid
- you only need a lightweight DNS resolver for a single machine rather than a full server
- you need a highly specialized enterprise DNS appliance with vendor support
- you cannot run .NET or Docker on your host environment
