I believe Barry is correct, though I haven't tried deleting a host record
while it is in use, so I can't be sure.
I don't know if all registrars support "renaming" a name server, but OpenSRS
does. The host name or IP address of a name server can be changed. I know
because I've done it.
And yes, an IP address can only be used by one name server. I've tried
adding a host record with the same IP address as an existing one and the
registrar rejects it. I've heard that this will change relatively soon, but
I'll believe it when I see it.
What is interesting is that, even though the registrar requires each name
server to have a unique name and IP address, the old name persist in the NS
records for domains in *some* ccTLD servers (but *not* gTLD servers) after
renaming.
