You have a number of internal hosts whose DNS entries are stored on an internal DNS server. However, all other (external) hosts need to be resolved by an external, e.g. ISP, DNS server. How do you split these DNS requests?
Point your primary DNS group to your external (e.g. ISP) DNS server.
Create a new DNS group (called localdns in this example).
In this new group, identify the IP address of your local DNS server(s) and your internal domain(s).
