This is a fallacy.  The fact that the depletion rate has been common knowledge 
for quite some time doesn't mean, as you would have us believe, that there is 
no issue.

IANA depletion day is in 2 months and 5 days.  The first RIR depletion is 335 
days out.  Provider depletions will happen very quickly afterwards.  You seem 
to be under the impression that people have been crying wolf.  You're wrong.  
The wolf is at a known distance, and travels at a known (and increasing) rate 
of speed.  Just because you can't see the wolf doesn't mean everyone has been 
wrong this whole time.

And no, there aren't 'large blocks of IPs which are very underutilized'.  There 
are /8's that can't be broken up for practical reasons, but we're burning 
through those in 30-40 days now, so it doesn't matter if they were returned to 
the pool.

This is a very real problem.  Please stop spreading FUD.

Nathan
