The only place in which people have noted that there is a possibility of running out of bits in the existing IPv6 addressing hierarchy is when they look at a model where every residential customer gets a /48. In that scenario there is a possibility that we might runout in 50 to 100 years from now. Is it even a possibility then? A /48 to everyone means 48 bits left over for the network portion of the address.
That's 281,474,976,710,656 /48 customer networks. It's 16 million times the number of class C's in the current IPv4 Internet. Am I just not thinking large or long term enough? -Don
