Can I register my name server by more than one name, with a single IP address?

Okay, I understand.
It's no problem at all to have more than one domain name pointing to the
same address, and then using those multiple domain names in NS records.
VeriSign Global Registry Services, which runs com, net and org, used to
insist that each name server registered have one and only one name, but
I believe that restriction went away recently. It was never a technical
restriction, anyway.
Just because a name server has multiple names doesn't mean there's
anything different about its configuration. It can still be just a single named
process listening on a single IP address.
