The company I work for is going to switch hosting providers. The problem is that our DNS server is going to have to switch IP's once we move over to the new location. Now I can go and change all of the domains that I have registered over to use the new DNS server, but we have many (irresponsible) clients that have their domain names using us for DNS.
Is there any way to do a global change for all domains that have my DNS machine listed as their primary DNS, even if I do not own the domain?
My first thought is "No". This would be way too insecure, because how would I prove that I have the rights to do this? Then I began to think. When you register a domain and point it at a DNS server, it asks you for name and IP. If I were to move my DNS server and merely change the DNS entry for that machine to point to the new IP, would DNS queries look for the old IP, or use the domain?
Has anyone experienced a similar problem? I do not think having all of our customers manually edit their configurations at their registrars is an option....
