The rhetoric would have us believe that frequent renumbering with IPv6

yesterday we had to change an AAAA RR and PTR RR because one of our
servers got a new GigE interface to replace the old FastE. no part
of ipv6 renumbers seamlessly, from where i sit.
IPV6 renumbering was guaranteed to always be problematic when the address
was defined to include the MAC address of the adapter. A mystery to me
from the day I first heard the design but since there is nothing I could
do to expect to change the design, I've not bothered to to try and
understand the rationale.
