Abstract

Moving the Internet from IPv4 to IPv6 is crucial for the network to continue growing, but not every region is switching at the same pace. This report examines IPv6 adoption over five years, measuring various types of networks at different times. We used both active tests and passive monitoring to track traffic size, the Number of announced prefixes, the reach of dual-stack setups, and the uneven growth across regions. Our data comes from RIPE Atlas probes, APNIC records, and public logs of web traffic, providing a comprehensive view of how adoption evolves. We then developed a machine-learning tool to identify trends that align with policy changes, upgrades to network equipment, and various socio-economic conditions. The data show that IPv6 traffic increases noticeably after governments implement new rules or major Internet service providers upgrade their systems. Yet, we also found periods where growth stalled, primarily due to outdated hardware and slow migration by businesses away from IPv4. This report highlights both the technical gaps and regional delays, and it also identifies signs that may help predict where adoption will increase next. This information will help lawmakers, Internet providers, and Internet governance agencies design fair and effective IPv6 rollout strategies.
