Stateless autoconfig is hell when it comes time to make your DNS
entries match up with reality.  Swap out a dead Ethernet and (on most
machines) your address changes, and you better hope not too many places
have your old address cached.

Not to mention that it burns half your address space bits for, for many
smaller sites, approximately nothing.  (Admittedly, since this person
has a whole /48, it probably wouldn't be a problem in practice there.)

Besides, I thought A6 records had been backed off from and everyone had
to use AAAA records.  I just now had a look at gethnamaddr.c, and it
uses T_A and T_AAAA, but no T_A6.
