But the assumed model(s) need to be explained, in the draft, so that it is clear how those models apply to dual-stack-lite and to IVI/NAT64/NAT-PT -- all of which change the assumptions (due to lack of publicly-routable v4 address for some of those solutions). Or, alternatively, if it is this draft's intent that its model for v6-in-v4 is only intended to work if the CPE has a publicly-routable v4 address.
I'll expand on the relevant models for IPv6 transition mechanisms and dual-stack service providers in the next revision of the draft.
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? -- james woodyatt <jhw@apple.com> member of technical staff, communications engineering
