>From a client perspective, there is no difference between a) and b) - in both cases the client has no IPv4 address and all communications happen over IPv6 only. However there might be additional services provided to allow access to non-IPv6-enabled destinations. It might be a service provided by the network (such as NAT64+DNS64) or it might be smth on a host itself (464XLAT). So in general I'd expect the term "IPv6-only" to cover both a) and b) as b) is just a) with an additional service on top. -- SY, Jen Linkova aka Furry
