Thanks for your comments, they were very thoughtful.

IPv4 space is bounded (though very large), note that technologies
such as NAT, V6, and clever use of private space expand the supply,
though. Almost everything is limited ("buy land, God ain't makin'
any more dirt"). In general, markets are the most efficient mechanism
for the allocation of scarce resources. Prices aren't "set" in a market,
they are determined by supply and demand.

Use the inital money to fund root name servers, or the IETF, or the

I disagree. Market demand is shaped by aggregate utility functions
for the members in the market, obviously the utility of broken
routing is zero, and the price for a routing slot in a broken system
is zero. From the supply side, why would an ISP sell a route slot
that breaks their systems? The price for that would be infinite.

Yes, I agreee, but there are examples of market failure (e.g. little
sites wanting to multihome) that aren't met by the current procedural
scheme. Also, note that not all of the users of address space are
consulted -- only certain users get space from the registries. Indeed
most of the "heat" on the list has been generated by those that
feel have a stake but don't have a voice. In a market model, they

I'm not sure I follow. The routing slot market is controlled
by individual ISPs, IP space by a global market. Can you clarify your

Prices go up. What happens in a procedural based allocation? Do
you tighten the allocation and make it harder to get space? This
is effictively raising the price as well.
>And what if the equilibrium point for the number of route entries is much
You have an effective damper on route explosion, you have a market to
encourage renumbering, and you have a market to encourage deployment
of additional technology such as NAT. Sounds like A Good Thing to me.
How does the current procedural allocation have *any* direct control on
route entries? The current processes are indirect at best.

Why? A free market typically drives costs *down*. I'm interested
in your examples here. OPEC controls the supply of oil, how do
Evil Greedy Bastards control the supply of new IP space?
As a counter example, witness the Bass brothers debacle in trying to
control the silver market.
