What would be rational is for the complete address to be updated
at the primary server for the zone and propagated from there to
secondaries, caches, etc. That way, everyone gets the same view
of those addresses (modulo old cached entries), and if the address
is wrong, it's more likely to be noticed by "locals". With A6,
the various parts of an address arrive by different paths and
there is a greater potential not only for delay and failure, but
also for incorrect information that is not detected by the "locals"
for that address.
