alt Hacker NewsUnsurprisingly Google actually does also have IPv4 addresses. What they're measuring isn't "How did you reach our servers?" but instead "Could you have reached our IPv6 servers?"
So that measures everybody who has working IPv6. https://www.google.com/intl/en/ipv6/statistics.html
Where are you getting that claim from? Google’s page says “users that access Google over IPv6”.
To me the specifically does not say, “could you” reach the servers but “did you”.
