(or did I miss the point of the link-locals?)You don't. I don't think the point of link-locals has much to do withpinging customers... But since IPv6 routing protocols work over link- locals you don't need global addresses.If you want to ping your customers you should probably use a /126 so they can only use the specific address you give them. You need that anyway if you want to route a /48 or what have you to them. BTW, there is discussion about rethinking /48s for customers in IPv6. Thoughts?
Where is this being discussed? What sizing is being discussed? I'm expecting in the long run some ISPs will hand out /128s in the hope that this will once and for all keep customers from putting more than one device on a connection (of course that would be followed immediately by implementations of NATv6 if it happened).
There is a draft pending in the IETF V6OPS WG (draft-ietf-v6ops-nap-01.txt) that relies heavily on the fact that everyone and his dog gets a /48 to justify the reasons IPv6 solves the world's problems that were previously solved to varying extents by NAT boxes. If the /48 thing is being discussed somewhere, that would significantly alter the underpinnings of the draft's arguments.
