Unregistering a nameserver?

[syanet]

How would this be done. I registered 2 IP's I have as nameservers, but no longer go by that name. I want to use the same two to point somewhere else now. My registars control panel has no where to do this. Is there any other way?

You don't need to un-register them you can have multiple nameservers pointing toone set of ips well i did with webnetics i used there ips for my nameservers which i never used since it was a pain in the butt.

I tried to register the origional 2 IP's under a different name, and it gave me an error saying I need to use unique ones. I assume this is because I already have them registered under a different name.
