I’m stuck on stage 8 of dns resolver. I am trying to forward request to resolver and it doesn’t seem to work. I’ve tried to use UdpSocket::send_to(..) and UdpSocket::recv_from(..) and this doesn’t seem to work. I get response here, but it looks like the response I receive is not from the resolver. …

Finalllllyyyyy… I wish test could somehow find out these small details. Looks like the issue was I was sending qr flag as ‘reply’ (1) when forwarding the value to another dns resolver. After I made an update to send a qr value as (0) to indicate the packet is for query it worked.
