IPv6 does allow you to have a client on any ISP to not rely on IPv4: NAT64/DNS64 is one example for a home network (my experience). There are major mobile carriers that will also disagree, and they provide an IPv6-only technical solution.

> It's hard to estimate how increasing percentage of users with IPv6 access is impacting the demand for public IPv4 addresses.

I'm more interested in this excellent point you make, about the economics. I don't think this has been thought through as well as the technology.

And can we please find additional sources other than GOOG for IPv6 adoption?
