- Google's measurements indicate IPv6 has reached 50% adoption among its users, marking a significant global milestone.
- IPv6 adoption varies significantly by region and economy, with countries like India, Vietnam, and Saudi Arabia showing different adoption curves than the global average.
- APNIC Labs reports 42% worldwide IPv6 capability, differing from Google's figures due to statistical weighting based on internet user populations per economy.
- APNIC's measurement uses advertising via Google Ads to collect data, applying weighting to reflect global internet usage rather than daily ad distribution patterns.
- The internet operates in a 'two-protocol world' with IPv4, NAT/CGNAT, and IPv6, where interoperability relies on higher-layer protocols like TCP, UDP, and QUIC.
- Deploying IPv6 requires substantial technical effort and investment, with newer market entrants often adopting it to reduce costs, especially in mobile networks like Reliance Jio in India.
- Despite adoption challenges, IPv6 is now a mature, globally deployed protocol used across fixed and mobile networks, integrated into daily internet operations.
- Current IPv6 issues include limited support from some major websites (e.g., GitHub), incomplete coverage in IT education, and gaps in ISP deployment timelines.
- Both Google and APNIC data show a linear growth trend in IPv6 adoption since 2018, with projections suggesting continued progress toward 2030.
- IPv6 adoption may be higher than measured, as Google's statistics exclude China, and major content providers/CDNs with IPv6 deployment drive significant unseen traffic.
