Yeah, and they both piss me off, because they don't take into consideration
real-world politics and staffing.

Before iWarp got our own class B, we were a range of addresses (pseudo
class C) under Intel's class B, which was administered by one
overworked guy (hi Jeff).  Jeff had not gotten around to asking CSNET
(yet another level of indirection and administration to deal with) to
provide in-addr.arpa service for us, so I was stuck out in the cold.

I could get out on the net (because the routes were right), but uunet
and a few others kept bumping me.  And there wasn't anything I could
do about it.

Course, now, I got my own class B, and in-addr seems to be working
fine (although CSNET is still handling it for me, and I'm pretty close
to taking it over myself).

I can imagine *very* similar circumstances in most of the big
companies (company gets class B for "everyone" because of politics,
but doesn't support it).

So, once again... *don't* kick us off because of things we cannot
control!  (And yeah, I *am* the friggin admin, so telling me to see my
admin doesn't help!)

Just another disgruntled admin playing "technically feasible" against
"politically correct",
