Hi, It seems that a real world problem case is not covered by this update: tunneling v6 over v4 when there is a legacy CPE NAT in the way, in an ISP-managed way (unlike Teredo). At the moment this is a well known but orphaned problem, which will remain with us until the last NAT44-only consumer CPE device has gone.
It's certainly the case that this scenario doesn't quite match RFC 4925 and doesn't need to "support all combinations of IP versions over one other." However, that is just a matter of charter wordsmithing. Nit: there's a reference to NAT-PT; maybe it should be NAT64 these days.
