Hello:
I have our DNS hosted with the ISP at the same time would like to setup
an additional setup within the office where in I can add only
additional records not present in the primary DNS hosted with the ISP,
these are usually servers yet to be deployed at the hosting center. How
do I go about it. The ISP doesn't allow zone transfers and so I cannot
create a full fledged secondary dns server. I presume I would need some
kind of forwarder so that it queries the primary DNS servers in case
the record was not found in the set at the office. Where should I
start?

Thanks
