Hi Jiaxin,

Thanks for the information provided.
Even I have gone through the RFC but wanted to double check.

Thank you
Naveen

Subject: RE: can the DNS driver relays the request?

Hi Naveen,

I think you mean the DNS relay is that one DNS client sends the DNS queries to 
the relay, then the relay sends the queries to the DNS server or whatever is 
set in the router's settings.

I checked the related RFCs of DNS and can't find the related definitions of 
that, but I believe it's the router's capability to provide the relay service 
just like the DHCP relay. Currently, it have been supported by some routers 
(D-Link or Cisco) but may need your another simple configuration (I'm not sure 
because I haven't tried that).

Besides, in the case you do need the support within the client, you can code 
the app/driver to handle the request first, then call the DNS driver APIs 
provided in NetworkPkg. I think it's the way to relay the request.

Thanks,
Jiaxin
