See there's a lot of stuff out there - currently only in vendor documents / IPv6 forum publicity material .. Toasters, phones, cars etc with v6 stacks. Which might exist.
The number of devices inside a /64 is fully irrelevant to the discussion, because there is no way to exhaust a /64 with physical devices. The only interesting question here is - are there enough "ISP sized chunks" to number each company that could reasonably show up at a RIR and declare to be an ISP - are there enough "end site sized chunks" to number each possible end site (home user or corporate customer) and if you do the math, and look up a few things in Wikipedia, like "population on earth", you'll see that indeed, 64 bits of prefix space is a lot. It's not enough to give ISPs a "class A" (/8), "class B" (/16) - but giving ISPs a "class C" (/24) each should even work out. But we're not doing that, we give whole ISPs the equivalent of a single IPv4 address (/32). Gert Doering -- NetMaster -- did you enable IPv6 on something today...? SpaceNet AG Vorstand: Sebastian v.
