So how big would you like addresses to be, then?
We currently have 1/8th of the IPv6 address space set aside for
global unicast purposes with the idea that ISPs give their customers /
48 blocks. That gives us 45 bits worth of address space to use up.
It's generally accepted that an HD ratio of 80% should be reachable
without trouble, which means we get to waste 20% of those bits in
aggregation hierarchies. This gives us 36 bits = 68 billion /48s.
That's several per person inhabiting the earth, and each of those /
48s provides 65536 subnets that have room to address every MAC
address ever assigned without breaking a sweat.
What was the problem again?
