A hoster can get /48's for each customer. Each customer is technically a seperate site. It's this stupid desire to over conserve IPv6 addresses that causes this not IPv6.
In theory, yes. In practice, I'm skeptical. I think many will sub-delegate /64s
Plus, nobody has yet addressed the fact that new /48s will be just so EASY to obtain since they are going to be plentiful... therefore... the LACK of scarcity will make hosters and ESP... NOT be very motivated to keep their IP space clean... as is the case now with IPv4.
The brakes are already in place at the RIR level. At this level you can't just get more /48's with no accountability.
Also, it seems so bizarre that in order to TRY to solve this, we have to make sure that MASSIVE numbers of individual IPv6 IP addresses.. that equal numbers that my calculate can't reach (too many digits)... would all be allocated to one single combined usage scenario. Then allocating only /48s multiples that number by 65K. Mind boggling
There are 281474976710656 /48's. That is what you manage, not IPv6 addresses. It's also most probably got more digits than you calculator supports. :-) Stop thinking addresses and start thinking sites. We went to 128 bit of addresses so that we could stop worrying about individual address, the sizes of subnets or working out how many addresses a site needs when handing out address blocks except in the most extreme cases.
