He may be downvoted because counting that is a bit disingenious. The central concept in v4 is an interface, which has a 32-bit address and of which a host tends to have one. The central concept in v6 is a network, which has a 64-bit address and which may be populated by one or many hosts. The number of /64 network addresses per m² of the planet is also a large number, I'm sure. (That it is a large number is intentional, in order to permit simple routing even when that simplicity leads to lower addressing density.) But counting that is honest in a way which counting /128 addresses isn't.
