higher penetration of native v6, I would restate that a bit more conservatively as
Google's statistics are likely a fair barometer for USA usage in the large content provider arena which have a strong mobile representation.
AT&T, Comcast, and Charter/Spectrum, the three largest cable companies, have IPv6 support. I expect a lot of Google searches and Gmail messages come from them, too. I think it's more accurate to say that large networks have looked at the costs and implemented IPv6. Small networks, many of which have no need to expand beyond their existing IPv4 allocations, largely have not. Of course, there are a lot more small networks than large ones, even though they don't necessarily represent many users, so guess who we hear from? R"s, John
