Five Security Flaws in IPv6

Iljitsch,

Currently IANA has 46 /8s left in the free pool, so that's -9 from  
the end of 2006.  We're not yet at the midpoint of the year, so -18  
for 2007 looks to be pretty dead on.

And why would you assume a linear extrapolation (55/3 = 18 rem 1) for  
the last 3 years of IPv4 free pool availability?

Rgds,
