Good News, everyone!
IPv6 adoption continues to double, year on year. Of course, that’s only three years of baseline, but things are certainly moving in the right direction.
As this article points out, if this rate continues, more than half of Internet users could have IPv6 within 6 years. This goes along with estimates of IPv6-only customers reaching 20% by 2017.
It remains to be seen if this adoption rate can continue. However, events such as Switzerland moving from 3% to 10% adoption in a single month are interesting. They show that a single large ISP can quickly make a huge difference in adoption rates, as they turn up large portions of IPv6 connectivity in large deployment events. I expect Comcast to quickly begin to have a similar impact on US IPv6 availability later this year.
