Re: Assigning IPv6 /48's to CPE's?

Do you really think that today's allocations are going to be in use
(unchanged) when people are building homes out of IPv6-addressed
nanobots, or when people are trying to firewall the fridge from the TV
remote, etc.?
I certainly hope not- but then again I never thought IPv4 would be around this long either.

I understand trying to plan for the future, but if
someone is setting all this stuff up, getting a new (and larger) IPv6
block from their ISP is going to be the easiest part in the process.
You're right of course.

Again, why the hang-up on 8 bit boundaries?  Why not /52 or /60?  /60 is
not much bigger than /64, but /52 gives an end-site 16 times as many
subnets as /56 while giving the ISP 16 times as many blocks as /48.
Because byte alignment makes for shortcuts in routing softare/hardware allowing higher speeds? Because ARIN says so? :)
