but of course.


This is a different graph - it is a probabilistic graph that shows the predicted month when the RIR will be down to its last /8 policy (whatever that policy may be), and the relative probability that the event will occur in that particular month.

The assumption behind this graph is that the barricades will go up across the regions and each region will work from its local address pools and service only its local client base, and that as each region gets to its last /8 policy the applicants will not transfer their demand to those regions where addresses are still available. Its not possible to quantify how (in)accurate this assumption may be, so beyond the prediction of the first exhaustion point (which is at this stage looking more likely to occur in July 2011 than not) the predictions for the other RIRs are highly uncertain.
