GoKawiilYou may have seen headlines noting that Google’s measurements have shown IPv6 reaching 50% for the first time. These measurements are based on Google’s continuous monitoring of the availability of IPv6 connectivity among its users, and reflect the proportion of users who access Google services over IPv6. Reaching the 50% mark is a significant milestone, demonstrating that IPv6 is a mature, fully capable protocol that is being deployed at a global scale and used effectively in real-world networks.

The shape of IPv6 adoption isn’t evenly distributed
The global uptake of IPv6 follows a complex and varied path that isn’t apparent in a single, aggregated trend line. Google does not publish per‑region IPv6 statistics, and its per‑economy data is limited to overall totals, so these nuances are hard to see in Google’s figures alone. To understand how adoption really unfolds, it’s more instructive to look at the APNIC Labs data. Individual economies such as India, Viet Nam, and Saudi Arabia exhibit adoption curves that differ markedly from the global average. As the APNIC Labs data shows, this global trend does not necessarily reflect the experience of individual economies.
APNIC’s own measurement records a 42% worldwide IPv6 capability (Figure 2). That’s a substantial difference, which also needs clarifying.

Measurement differences
APNIC’s measurement program is run by APNIC Labs and uses online advertising distributed through Google Ads, which appear in end users’ web browsers, games, and apps wherever Google advertisements are placed. APNIC does not select specific users and seeks the broadest possible exposure in every economy, 24/7. Normal advertising tracking systems are used with APNIC Labs logic, which ensures a unique set of tests are run, measuring IP, BGP routing and DNS, amongst other technology choices. No end-user Personally Identifiable Information (PII) data is held, and raw measurements are never shared, only collations at the ISP, economy and region level.
This work is carried out with the assistance of Google Research, ICANN, and others who help fund and support the activity. Given this close involvement, it’s natural to ask why APNIC’s measurement results don’t always align with Google’s own published statistics. If Google is used to conduct the research, how can the results differ?
APNIC’s measurement approach applies statistical weighting to the collected data and uses external sources, such as World Bank statistics, to model Internet usage by economy. This is necessary because the number of measurement samples APNIC Labs receives each day is not uniform. Advertising placements are optimized by Google to maximize delivery and revenue, which means that, on any given day, more advertisements, and therefore more measurement samples, may be shown in certain economies than others. For example, if advertising demand is higher in North African economies such as Egypt or Tunisia on a particular day, more measurements will be collected there, while fewer may be gathered from South America or Asia.
