said by Napsterbater:You do have local IPs they are called Link local IPs They only work in the same broadcast domain though so a tad different then the LAN IPs of IPv4, since you can not route them at all.
AFAIK there is no way to have a dynamic subnet behind a router that would be assigned from the provider, It would have to be a static subnet, Altough from you ISP's address pool.
but if you use a switch only (or a transparent firewall) all the local client could receive IPs via DHCPv6 or auto-configuration.
Again depend on how they implement it.
I posted something a few minutes ago. There is a standardized mechanism that providers can leverage to delegate IPv6 prefixes to subscribers/users. RFC3633 defines that mechanism in case you are interested. This mechanism does in fact leverage DHCPv6 (RFC3315) to delegate IPv6 prefixes using the providers DHCPv6 infrastructure.
