To my knowledge this cannot be done.  I will be more than willing to be
corrected, but that is what I have heard and have been told.  Likewise, it
would eliminate the need for .dhs.org address for @home users (not that I
did anything like that).

Right, it needs a dns entry... it it trying to lookup that IP as a name,
and it is failing.

If you are using publically addressable IP space, I would forgo the DNS
server and get a .dhs.org account.  Going to www.dhs.org will get you on
your way.  I have used one for well over a year with no problems... they
were formed from the ashes of ml.org.  You will basically get *.dhs.org.
It is well worth the money (it is free as in beer).

If you are using non-routed IP addresses... then well, pickup the bind
book and start hacking.  I know of a guy who created his own private dns
tld... .foo  That way it would not be routed out onto the net.  There are
probably some how-to's online to pull this kinda thing off.
