When you consider that the default starting ISP size is /32, and that is 
sufficient to address something less than 64k subscribers, purist style, 
in broadest possible theoretical terms the following emerges.

a) ipv6 has one ISP per every 1.x human (enough?), IPv4 has one IP per 
every 1.x human (not enough)

b) IPv4 has 64k ISP's capable of servicing 64k customers, IPv6 has 64k 
multiples of that.

So that will be one paradigm shift and one order of magnitude 
(exponentially speaking) for your total.

There is plenty more to wonder about, for example, will the rest of the 
unicast space get Class E'd?
