I currently host my own external DNS server and will continue to do so. We are about to switch ISPs however and of course we will have a different range of IPs then. I thought all i would have to do is contact internic or my domain registrar and have them change our NAME SERVER records to point to whatever the new IP address of my DNS server will be. However I was surprized when i looked at my domain on Internic's website and notices that NAME SERVER records aren't listed as IPs but rather by FQDN DNS names. So in my case my NAME SERVER records would not be changed since they are already correct (NS.mydomain.com) for example. My question is how and what do i need to change so that top level .com servers will "know" that my NS.mydomain.com IP address will be different? To me it would make perfect sense if the NAME SERVER records were just IP addresses b/c then you could just change it there, but they aren't.
