	I think you miss my point.  The point is NOT what IP address you
use on your internal LAN.  The point is that if you have an assigned IP
address, it is not yours to transfer to someone else for use on the external
network.  That IS the Internic's domain to dictate.  If you tell them that
you have this nice lovely Class B network that you are no longer using and
you want to sell it to ACME Widgets and Dancing Girls, they're going to say,
no you don't have it, if your not using it you're suppose to give it back
to us.  This has nothing to do with what you use on your internal network.
They will simply refuse to acknowledge any use or routing of the network
outside of what they assign, so your assignment then becomes worthless.

	If your company says, "Well, we have an obligation to our stock
holders to sell this address to the highest bidder and not turn it into
the Internic."  What are they going to do when the Internic refuses to
acknowledge that sale?  They just say that you didn't own it so you don't
have the authority to transfer it or sell it.  You could try suing the
Internic, but I think they've got this pretty well documented and I would
not like to be the one trying to find out how well it would stand up in court.

	If you can't get the registration officially transferred you can't get
the address routed.  Check out some of the docs.  Portable (not assigned to
an ISP or associated with an autonomous system) addresses are NOT guarenteed
to be routable.  How much is that Class B worth if the routing does not come
with it?

	My point was that the issue of stockholders was largely irrelevant
to what the Internic was or was not likely to do.  It is possible (I know
from personal experience) to do this but is very treacherous.  Whatever
you think your obligations to the stockholders are, you must proceed extremely
cautiously here.  If you go to the Internic and tell then that "we aren't
using these addresses any more and we've sold them to these guys now",
they're going to tell you that 1) You can't do that and 2) thank you very
much for notifying us of an unused class B block, we'll add it back to the
pool right away!

	My method would be (was) to assign a chunk of the addresses to the
other party and route approriately.  At some point in time, transfer control
of the addresses (Organization name, POC's, etc, etc, etc) to the other
company and document the fact that the address is still in use by BOTH
parties.  At some future point in time, retire the use of the addresses by
the first party and change the routing.  In my case, this was largely the
result of the sale of a company division to another company (Yes - we almost
lost the entire network because of that) and subsequent attempts to transfer
the registration to the new company.
