In an earlier post in mid-2016 we highlighted the enormous progress that four major US mobile providers were making with IPv6 deployment by obtaining aggregated data from our measurement sources. The four networks in question:

• Verizon Wireless (AS6167, AS22394)
• T-Mobile USA (AS21928)
• Sprint Wireless (AS3651, AS10507)
• AT&T Wireless (AS20057)

At that time we were excited to note that the majority of traffic on these networks to major Internet content sources was now being transported over IPv6. As we start another year for IPv6 deployment and measurement we thought it would be timely to take another look at the state of IPv6 deployment in this segment.

The graph below shows the progress of the aggregate metric for IPv6 deployment in these four networks over the last two years.

This is really striking and consistent progress since we last reviewed the situation, and the growth of IPv6 deployment in 2018 across all network types and geographies is showing no signs of abating. Check out the full listing of newly updated IPv6 network operator measurements for this month.

If you’re a network operator deploying IPv6 and would like to join these cellular networks and the other networks that make up the ranks of World IPv6 Launch participants, please register your network for measurement.
