What is SlowDNS? How It Works?

A DNS tunnel is one way of circumventing network censorship. A recursive DNS resolver's purpose is to receive packets and forward them somewhere else—in effect, working as a kind of network proxy. DNS tunnels over plaintext UDP are generally considered easy to detect because of the unusual DNS messages they use. However DoH and DoT are encrypted—an outside observer can see that you are communicating with a public resolver, but cannot decrypt the raw DNS messages to see that they embed a tunnel protocol. (The resolver itself can still easily tell that you are using a tunnel.)
