Can a single 2008 R2 DNS server cater for two client subnets?

Hi, on my premises I have two client subnets - 10.1.1.x and 192.168.1.x.
The 10.1.1.x subnet has access to a VPN which connects to another site - let's call it .
The other subnet does not have access to that VPN.
Clients on both subnets currently use the same DNS server -

The computer has an internal IP address of and an external IP address of

I would like to configure my DNS server so that:
if a client on 10.1.1.x asks for the address of, it will be given as the result;
if a client on 192.168.1.x asks for the address of, it will be given as the result.

Is it possible to do this on a single machine? Or will I have to get a separate DNS server for the 10.1.1.x subnet?

All suggestions gratefully received!

You are describing split brain DNS.
In Windows Server 2008 R2.  No, you can not do this with a single implementation of DNS.
In Windows Server 2016, in theory you can with DNS Server Policies.

Thanks Rich, I had seen articles on split horizon and split brain, but none related to 2008 R2. Your answer explains why! Thanks for your help - I love a quick answer even when it's 'No'! :)
