Ask HN: Which VPS hosting providers supply native IPv6?

Now that IPv6 is supported just about everywhere in desktops and servers, which hosting providers can supply global IPv6 connectivity to their VPS offerings? It isn't enough to just support IPv6; they also have to provide transit to the IPv6 Internet and IPv6 connectivity to the IPv4 Internet via a gateway.

With a hosting service like this, it is feasible to go to 100% IPv6 only inside your own network.
