Last year, I wrote about the evolution of IPv6 deployment viewed from a per-country perspective from 2014 to 2024.
In mid-2024, we observed 13 countries with 50% or higher levels of IPv6 deployment based on combined measurements from Akamai, APNIC, Facebook, and Google. Reviewing our most recent data shows 21 countries with 50% or higher IPv6 deployment.
The new kids on the block include Brazil, Guatemala, Hungary, Japan, Mexico, Puerto Rico, Sri Lanka, and Tuvalu. Check out the bar chart race below to see how these countries entered the majority IPv6 club during the last 12 months.
Tuvalu’s explosive growth in IPv6 deployment is something to behold, although perhaps not surprising given that, as of 2023, the country’s population was less than 10,000. The sudden growth in IPv6 since the beginning of 2025 can be explained by the arrival of Starlink’s LEO satellite Internet services in Tuvalu.
According to APNIC measurements, Starlink is the only ISP available in Tuvalu providing IPv6 service. My colleague noted this same effect in several countries in Africa. Read: Africa’s IPv6 Deployment is Taking Off
Also, according to APNIC, countries in its service region now exceed 50% IPv6 deployment in aggregate.
Who Will be Next to Join the Majority IPv6 Club?
Countries with more than 40% IPv6 deployment currently include Mongolia, Portugal, Finland, Nicaragua, Canada, the United Arab Emirates, the United Kingdom, Estonia, and Thailand, which has a deployment of more than 49% currently.
| Country | Current IPv6 capability |
|---|---|
| Thailand | 49% |
| Estonia | 46% |
| United Kingdom | 45% |
| United Arab Emirates | 44% |
| Canada | 43% |
| Nicaragua | 41% |
| Finland | 41% |
| Portugal | 40% |
| Mongolia | 40% |
What is IPv6?
IPv6 is the latest version of the fundamental technology (Internet Protocol) that powers the Internet. The previous version, IPv4, still operates on many networks worldwide but can only support an Internet of a few billion devices. By contrast, IPv6 can support an Internet of billions of billions of devices and provide enough address space to meet the needs of the growing Internet for decades to come. Simply put, the Internet has outgrown its original design, and IPv6 is the solution.
Internet Society Pulse presents measurements of IPv6 adoption to raise awareness of the different levels of IPv6 adoption in other countries and networks around the globe and to encourage greater adoption of this critical enabling technology. Learn more.
