That's basically what I'd been trying to do, only I was using the internal IP for the records, and the domain manager system of my registar wasn't accepting the new NS values. It seems to have worked this time. So thank you very much!
Must wait and see once propagation is done though.
Another thing: I seem to have been mislead when thinking I had a static IP. I'm getting cable internet and the DHCP had kept me on the same IP for several months, but I just unplugged the modem and reconnected to see and I now have a new address. My router has a DynDns function, can I then point the nameservers/records to the IP of my DynDns? can that work?
