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).
PS: Sorry for a silly question
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.
