DnsTT Client

dnstt is a DNS tunnel that can use DNS over HTTPS and DNS over TLS resolvers.

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.)

dnstt uses end-to-end encryption and authentication between the tunnel client and tunnel server by default. Its protocol design enables higher performance than other DNS tunnels.
