We host DNS records for several domains on one of our DNS servers. We have changed that name server's IP address. We changed the A record for our name server (ns2.example.com) to the new IP address. How do we change the IP address of our name server with the root servers? When you look at the domain servers for the various domains our servers are responsible for, the old IP is still listed beside ns2.example.com. Does anyone know where we'd go to change this? The domain was initially registered at Network Solutions and now it's registered with Tucows (if that makes any difference).
