If you see IPv6 as a solution to the exhaustion of IPv4 space, take a

massive growth in both the RIB and the FIB in the process.

I am actually more concerned with the CPE problem and how to make autoconfiguration work for end users.

For instance, should we assign /64 to end users and have them do whatever they need (subnet to /80 if they need more than one network)? We need to provision routes in whatever routers connect to customers, which I guess is the FIB/RIB-problem mentioned above?

Is there general agreement that IPv6 requires a router at the customer prem to scale (ISP doesn't want to know what the end user devices are)?
Also, is it ok to statically assign /64 to end user or should end user be able to switch addresses (some like dynamic IPs because it's not persistant over time and like the "privacy" you get by changing IP all the time).

I haven't been able to find a BCP regarding the end user equipment and how to configure it, does anyone have any pointers?
