Two DNS at same server (same physical machine)

Lets say I have two IP addresses on a single Small business Server SBS 2011 server.
192.168.0.2 & 192.168.0.3

I want that if the query comes on 192.168.0.2; DNS server forwards it to 208.67.222.222
and if query comes on 192.168.0.3; DNS server forwards it to 8.8.8.8. Rest remains same (resolution of local records)

Is it possible on the same DNS server or do I need any third party DNS server to be installed on the same physical machine.

If I have to install another 3rd party DNS server on same physical machine then I guess, I have to manually import all the existing DNS records from existing DNS server to newly added DNS server.

one of the 3rd party DNS:
http://dhcp-dns-server.sourceforge.net/

looking for more simple GUI DNS if required.

I'm about certain that this can't be done with only Windows DNS server (not even sure if it can be done with third party software).  Maybe if you bind one DNS service to one IP and the other to another IP.

Can't think of why you would want to though.

footech is right. I don't think windows will do this. you would need third party DNS and configure it to bind to a single IP and then configure windows DNS to bind to the other IP.

Answer to the query Why I do need this? Pls go through the following thread:
http://www.experts-exchange.com/Hardware/Networking_Hardware/Firewalls/Q_28522323.html#a40334720

Yes, I would bind MS DNS server with one IP & another instance of DNS (may be 3rd party) to another.
WHich 3rd party DNS would accomplish this in most easily & stable way?

Using active directory and a quality router/firewall you can accomplish this AND increase the security of your network.  Since we don't know what your geo is hard to recommend a particular piece of kit.

Managed to setup additional DNS server on the second IP address using
http://dhcp-dns-server.sourceforge.net/

The client computer is getting correct IP of all the hosts .


Except:

_kerberos._tcp.Default-First-Site-Name._sites.dc._msdcs.myname.local
_ldap._tcp.myname.local
_ldap._tcp.Default-First-Site-Name._sites.myname.local

 is not found, thats why having issue while connecting the AD & Exchange.

getting error in DNS log files that this does not found in forwarding server.



I guess this must not be forwarded to the forwarding server but must resolved locally.

Please guide.
