With the current process, renumbering servers can be a lot of work:
imagine arranging for (say) twenty different TLD managers of varying
responsiveness and with different first languages to send the same
message at roughly the same time to IANA, and then imagine the
collation exercise required at the IANA to match together the non-
synchronised and inconsistent requests that actually arrive.
This perhaps goes some way to explain the observed actions of TLD
nameserver operators to either avoid or limit the pain of renumbering.
Many servers are now numbered out of PI /24s which are used for
nothing else; the RIPE NCC's approach (of not re-using the same
nameserver name) has already been mentioned.
Randy's goal of adding an AAAA record in the root zone to rip.psg.com
is, in effect, an exercise in renumbering (even though it's adding an
address, rather than changing an existing one).
Based on what I've seen, the pragmatic approach is:
1. Renumbering is hard, but there's no workaround, so get ready to
endure the pain.
2. Do what you can to avoid having to experience the pain again.
In this case, (2) might involve not only adding the AAAA (and,
ideally, doing so from a PI /48 assigned under an RIR's critical
infrastructure policy, and never using that /48 for anything else),
but also renumbering rip.psg.com's IPv4 address into a similarly PI /
24. If there was ever a desire to change the name of the nameserver,
this would also be the time to do it.
This doesn't fix anything for anybody who follows, of course.
