Right.

Right again. And like prospecting for oil, at some point you're  
burning it up faster than you can prospect it.

There are some 45 - 50 /8s assigned to single organizations. Let's  
assume for simplicity that those can all be reclaimed. That's 4 years  
at a /8 a month. So far so good. Then there are 40 - 45 /8s in class  
B space. That means 256 times as much effort to reclaim the address  
space, or reclaiming about 10 class Bs a day...

Predicting is hard, especially when it concerns the future. But one  
thing is certain: we live in interesting times.
