Legitimate uses and justified need are equivalent statements that 
describe demand the community can support with supply, which is affected 
by scarcity, and that has always been the case. As such, the ARIN free 
pool is still wholly available to legitimate uses of resources, just 
like always.

The bar has changed, just like it has in the past.

Yes it is and yes it does. Or do you think the transaction we have seen 
should have been done from the free pool? And if not, does that mean 
that the transfer policy should be the focus of your ire, instead of the 
free pool?

If it is still occurring, it would be a year long temporary phenomenon.

Postponing requests due to increased difficulty results in negative 
benefit and is irrational behavior, unless you mean increasing 
efficiencies to compensate for the additional difficulties, in which 
case, I say again.

Working as designed.

If you assume that even half of the un-routed space is available for the 
market, or that half the legacy is available, or that a third of the 
broadband consumer addresses are re-usable or available for the market, 
you begin to doubt very much that the address market has any short-term 
hard limits.

We do not know how much inefficiency is available to be wrung out, but I 
have no reason to believe it be anything less than 25%.

Under a reduced by scarcity and market pressures utilization rate, that 
can last years.

We are so far beyond that point that it is salt in the wound to hope for it.

Project from this growth, rate when the demand for IPv4 addresses will 
die off. Put a number on it. Then let us agree to try to conserve the 
ARIN free pool to last that long.

Nobody has been switching to IPv6 because of this, so what makes you 
think they will soon?

This is your best case scenario? That IPv4 will become so untenable that 
it will force IPv6 adoption?

Unfortunately for this scenario, there is still no surety that there 
will exist a first mover advantage, even then.

Eventually the sun will burn out and Earth will be utterly 
uninhabitable. I suspect sometime before that, we will have migrated 
completely off of IPv4.

But I dont know when that will be. Neither do you. And as such, we must 
not treat IPv4 as disposable.

Horse trade? You support APNIC/RIPE style last /8 conservation policies 
and I will support 12 month free pool allocation.

Which is the most CGN targetable market. The cynical view is that the 
growth serves as a sanctioned form of stockpiling.

Do you think the ARIN free pool continuing to be available to their 
competitors may  have something to do with it?

And they can safely plod the course. It will still give them years of 
advantage. From availability, to supported, to desired, to consumed. 
Quite a distance.

You are correct. From an ops viewpoint, it sucks. Does it matter? Who 
calls the strategic shots? Ops?

IPv4 relevance is not decreased by the exhaustion of RIR free pool. RIR 
relevance is.

It is happening right now. So it is possible.

Lets not discuss fair. Because then we have to talk about things like 
who has the addresses and who does not. And who pays more and who pays 
less. And on whom the burden of obtaining these addresses is greater. 
And on whom is policy more burdensome. And who tends to find working 
with ARIN to be more difficult, frustrating and mystifying. And whom 
reaped the benefits of rir history that relative to now is increasingly 
more relaxed and informal.

Instead, lets discuss legitimate use. Justified utilization. Documented 
need. All things which ARIN, both operationally and as a matter of 
policy has gradually and ever increasingly been raising the bar on. For 
years. They certainly believe that they are applying policy soundly and 

The result is that ARIN still has a free pool to discuss.

Likewise,  I can sympathize with your desire to decrease IPv4 relevancy. 
However, I find your attempts to do so misguided and coy.

The AC has no business having an official opinion in this matter (and 
quite a few others) but that does not seem to stop them, so I would not 
worry about that if I were you.
