IPv6 has been available for a long time, but adoption is far from 100%. Google sees a huge percentage of the world's web traffic, and collects statistics about the way that we use the web - including how many people are using IPv6. The results are interesting, and show how poor IPv6 adoption is in some parts of the world. According to Google's statistics, fewer than 14 percent of the web as a whole have good IPv6 connectivity. There are some territories that have 100% adoption, but even the United States only has around one fifths of its users on IPv6 compatible connections - and in the United Kingdom that figure is closer to ten percent.
