Yes, typically you set the name servers for all the domains you host to the same: ns1.myhostingservice.com ns2.myhostingservice.com
Then you have host records in your myhostingservice.com DNS zone file for ns1 and ns2 with the IP's of your DNS servers, and can change them at will, allowing time of course for the cached records around the world to expire. When we relocated our data center (new town, new ISP, new Class C) we cut down all of the TTL's to 3 hours about a week or so in advance of the move, then once we were moved we reset them back up to what they should be. By the time moving day came, any DNS info out in the world 'should' have been well expired except for those with the short TTL, so it didn't take long for the world to get the new DNS data. In your case, the actual UNC server names don't matter - what matters is that all the domains have the ns1 and ns2 name servers in their domain registry record at their registrar because that's the starting point for resolving where to find a domain.

I'm sure someone will have a quick answer. Can you use and Alias record for a DNS server? Or, alternatively, does the server name on a domain name registration need to be the real server name? Does the registered DNS server name matter at all, or only the IP address? Here is my thinking: when we register a domain name, we list our DNS servers by name (e.g., server12.bcwebhost.net, or whatever) and that server's IP. However, how do we handle moving the DNS services to a new server without reconfiguring the registration information for every domain name that we manage? It is easy enough to move an IP address, but you wouldn't move the server name. It would be much easier if you made up a name, such as dns1, dns2, etc., that pointed to the appropriate server, but was independent of the real server name. Thus dns1 could point to server12 today, and to server 17 tomorrow. It would seem that I only need to setup an alias record for DNS1 and have it point whereever I want. So when I want to move the DNS services to a new machine, I would only need to move the IP address and change the alias record. If this isn't right (and I'm suspicious it's not), then is there a way to do this?
