Sounds good, regarding nameservers with domains in the registry. Using the
example above, a transfer of domain example.com would automatically transfer the
nameserver.
However a nameserver located "outside" the registry are owned by the registrar
who created it.
No problem if no IP address is set, but
example.com NS ns.example.jp
ns.example.jp A 212.227.1.1
Transferring example.com will not change ownership of ns.example.jp ... and if
the IP address of this server should be changed who is in charge of it?
Since the "alias" approach above minimizes the use of IP addresses:
Would it be useful to register nameserver outside the registry *without* IP
addresses only?
