I am quite stuck on #GT1

What i didn’t understand is,

  • Every dns message coming from client is now forwarded?
  • the dns message coming from the dns-resolver(where we forwared) is only answer(?) that we should include directly while sending response back to client?
  • and what about the answer from the yc9?
  • if gt1 satisy, yc9 disatisfy.
  • i am struggling on how yc9 and gt1 coexist(main problem)
  • i am doing on rust

can somebody explain steps of what i need to do?

i have figured it out, and also came to know that my question was silly.
→ every message is forwarded (dns message)
->dns resolver will respond will dns message as any other resolver
→ since yc9 test gives you the domain like,
“longassdomain” which resolver may not find, and responds with the buffer len equal to 12,
i made this checker,

if res_buf.len() <= 12 {
“respond with answer having random ip.”
}

idk if this maybe right way or not, but it worked!

Hey @onlykafle, would you mind sharing the content of the response when its length is 12 or less?

I’m not sure if the length alone is a reliable indicator. Seeing the actual response might help clarify.
