Considerations:
I don't know enough about how IPv6 are assigned today.
The idea is that the user gets a IPv6/64 Network address from their
Connection Provider like they currently get a IPv4/32.
So you can get one or a bank of addresses? Depending on the business
package? Note, we have a class C address.
The low 64 bits
are the Host Address. Normally this includes the device's MAC Address
although it can be a random number to prevent tracking the device via
the address. The user can use the high part of the low 64 bits to make
up their own LAN (like the current NAT mapping does for the single
supplied IPv4 address).
I think that is the "AH HA" I was missing. :)
So you can get one ISP provided IPv6 address and and use it for
internal addresses without needing a NAT?
So long as each user is given their own IPv6/64
network address this would avoid identification scaling issues vs the
current use of an IPv4 address (ie: Treat the IPv6/64 masked address as
the current IPv4/32 one is treated and you have the same granularity for
graylisting/etc. purposes).
Thanks. Very helpful overview.
