We have published the latest measurement results* for World IPv6 Launch network operator participants. We now present data for 73 networks, 65 of which are now exceeding the World IPv6 Launch target of 1% traffic over IPv6. New entrants include the Japanese ISPs Chubu Telecommunications and Softbank BB. Several of the 73 listed networks are now delivering more than 50% of their users over IPv6, and Gustavus Adolphus College network is delivering over 75% of their users over IPv6.

This update will be our final update for 2012, a year that has seen huge deployments of IPv6 technology all the way to the edge of broadband Internet services. We hope to continue our measurement work in 2013, so check back in the new year for news and follow us for the latest updates.

* Results are ranked by volume of traffic measured by Google. The percentages are a simple average of measurement results from multiple sources. Our measurement sources are Google, Yahoo! and Facebook and we have published results for all network operator participants for which we have at least two measurement sources and for which the simple average of those measurements is greater than 0.1%. Further detail on the measurement methodology is available here.
