This assumes a single machine scanning, not a botnet of 1000 or even the 1.5m the dutch gov't collected 2 yrs ago.Again, a sane discussion is in order. Scanning isn't AS EASY, but it certainly is still feasible,
With 1.5 million hosts it will only take 3500 years... for a _single_ /64!
I'm not sure that's what I would call feasible. -Don
