Final challenge: forwarding server, doubt regarding the resolver

General

I’m not sure I fully understand what’s being asked here. Do we run our own resolver on the specified IP and port received via the command line argument? Because when I tried to do so, I got “address already in use” error; from the test log, I can see this message:

[tester::#GT1] DNS resolver listening on 127.0.0.1:5354

So it ends up spawning a resolver by itself? If that’s the case, is our job essentially to just handle the query and response sanitization (per the conditions asked)?

Hi @tarun-verma, you don’t need to run your own resolver. The tester provides one for you.

Yep, that’s correct! Let me know if you’d like further clarification.
