To be clear, I'm by no means saying that we won't ever offer IPv6 addresses to shared hosting clients, this will inevitably happen. We just have no immediate plans to do so at this time because the need isn't there. Even the "want" isn't there, with maybe a handful of clients having even inquired about it over the past year.

Some ISPs offer IPv6 connectivity in some form or another but they're all going to offer IPv4 connectivity along side it either via dual stack or some sort of tunnel. IPv4 isn't going away any time soon.
