I know this has come up before; I have long been searching for specifics
on what needs to be updated.  Name servers?  Resolvers?  Caches?  I know
you can do this today with current and recent versions of BIND.  I have
heard that some Microsoft products may have problems with new RR types,
but real facts have been elusive.
