Hello, What does v6-only mean? a) A client only has v6 address and can only route to v6 destinations b) A client only has v6 address but can route to dual-stack destinations using a network translator (such as NAT64) IIRC, IETF SSIDs are named: 'v6 only + nat64’. Personally when someone says v6-only I presume a), but lately I have seen people say v6-only although they mean b).

It's not a silly question. In 2050 (hopefully sooner), IPv6-only will be a). In 2016, and for the foreseeable future, IPv6-only means (or will mean) b). IPv6-only customers will still need connectivity to IPv4-only Internet resources for as long as those IPv4-only resources remain in substantial order. An ISP ceases to be one if they cannot provide this connectivity. Mark.

hi, v6-only is v6-only: v6 client (no v4 assigned) -> v6 server (no v4 assigned) -- antonio

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.

put differently: "v6-only" only makes sense with regard to a specific machine, or set of load-balanced machines, or similar. If you bring in NAT64, forward proxies or similar, then "v6-only" as a term doesn't really make much sense anymore. That said, I'd call the combination of a "v6-only server" and a reverse proxy viewed as a whole dual-stacked.
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).
Don't forget a forward proxy in the DMZ of the user. That's what you almost always find in enterprise environments.
