    Whenever I try to do any operation on the name

It's segmentation faulting in the dn_expand routine under ultrix 4.1.

I used to sit in front of an Apollo called
"starbarlounge.cc.umich.edu", but that long name was still only 13
characters per part.  kfps-roble6-dynamic is 19 characters.  the way I
read RFC 1123 it requires it be able to handle 63 character host
names.  the way I read rfc 952 it says any part can be up to 24 characters.
allegedly there was a machine called
"car-crash-set-to-music.lcs.mit.edu", which should still be legal.

nothing in the multi-homed hosts discussion suggests that there is a
limit on the number of A records per host, but I might have missed
something.  kfps...6 has at least 26.  there's a kfps...7 for which
things seem to work, nice test case.

(at least until namedroppers or the bind list mangles it)
