Does Tor have its own DNS?
3 Answers. Tor clients do not, in general, directly do DNS requests. When you open a connection through the tor network you usually ask your client (on its socks ports) to connect you to a hostname and port, say www.example.com:80.

Are there any UDP ports on the Tor network?
Note that the Tor network does not support UDP connections, which is why some hacking is needed. If your client only supports UDP connections, the solution is to encapsulate packets to port UDP:53 on localhost as TCP packets using the following socat command:
