Sun, 14 Nov 2010 14:22:40 +0100 All I'm saying is, for the time being, catastrophic predictions that we're making the same mistakes as with IPv4 are a little dramatic and possibly premature. I agree with you that if every human gets a /32 we won't get very far, but for the moment, we still theoretically have about 13'000 IP addresses available for each kilogram of matter on Earth. Until we create matter out of nothing, I still think we're on the safe side. I don't doubt you disagree, and I'm ok with it :-) Le 14 nov. 2010 à 12:38, Eugen Leitl a écrit : > On Sun, Nov 14, 2010 at 11:27:06AM +0100, Romain Riviere wrote: > >> Ok, so let's allocate a couple /32 for all these machines >> and be done with it.
