The minimum set of models I think we should consider are..A) CPE is a router connected to a native IPv6 service provider with prefix delegation. Note: this includes dual-stack-lite CPE, as currently proposed.B) CPE is an IPv4/NAT router connected to a service provider where IPv6-in-IPv4 tunneling is available with a default route to the public default-free zone, e.g. 6to4, tunnel-broker, etc.Are there *any* other realistic models to consider for residential CPE?
Not that I see, understanding that 6rd (deployed by Free of the Iliad Group, and described in draft-despres-6rd-00) is in the list of B.
CPE is an IPv4/NAT router connected to a service provider where IPv6-in-IPv4 tunneling is available with a default route to a border gateway for the service provider, e.g., ISATAP (with private IPv4 address on the CPE's provider- facing interface).
- ISATAP is a tool that assigns full /128 addresses to IPv6 hosts of IPv4-only sites. - If my understanding of the subject is right, it is therefore not a tool to assign an IPv6 prefix to a router CPE behind which several hosts have teir individual IPv6 addresses. (A prefix shorter than /128 would be necesssary, typically /48 to /64).
