Consider two scenarios:
The end user has a simple computer, dual-stack
The end user has a LAN behind a dual-stack router
How will ISPs differentiate each one of these kind of users in IPv6?
An user in scenario
(1) would receive a single IP, whereas an user in scenario
(2) would receive a
/64 subnet (not sure if I'm correct on this one).
Will ISPs create 2 kinds of services (one for single IPs and one for subnets)? How does stateless auto configuration play a role here?
