Re: can the DNS driver relays the request?

["Wu, Jiaxin" <jiaxin.wu@intel.com>]

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
