Only if DNS is mis-configured.
One more incentive for people to keep their DNS working?

It is not critical, because the IN-ADDR zones work like that
anyway.  Although i agree that fixing DNS in that respect
would be helpful.

Oh, c'mon.  "Purity of idea" crap again.  TXT RRs were introduced
specifically for that purpose.

Depends on point of view.  I would say it IS desireable.

Then, as any lawyer would say you if you disallow Internet service
providers asking for renumbering you'll have to shut down telephones
first.  There is a very strong case that renumbering in communication
nbetworks is an accepted practice. (Can you say ISDN or X.25/X.121 or
Frame Relay)?

Yeah, sure.
