I'm honored.

c) assign IPv6 space and provide a transition mechanism.
d) put them behind NAT.
e) give them a smaller assignment than they could 
previously have justified and help them use it well.

I'm going out on a limb and say that the consensus is that
a market would be some degree of ungood.

If so, then maybe there are ways to prevent it, stall it, 
or make is less ungood.  Stalling long enough is equivalent 
to preventing.  There's a Soft Landing proposal that 
attempts to fill the gap, and several others.  Combined with 
"How can we prevent/stall/mitigate?" should be "How can we 
reduce demand for IPv4 addresses?"  These are not rhetorical: 
all are invited to respond.

I'm not sure we've asked them what it would take to get them
to use address space more efficiently and return the rest.
Um, "Hey, legacy holders!  What would it take to get you to
use address space really conservatively and give the rest
back?"


I have been much more opinionated here than I usually am.  I 
want to be very clear that I can't say what other Board 
members think, and I'm always open to changing my mind.
This message, and this disclaimer, are terser than the first
draft.
