Google reaches 50% IPv6 traffic

Google reports that IPv6 now accounts for 50% of its global traffic, up from 30% a year earlier [APNIC Blog]. The increase stems from Google enabling IPv6 across its core services, working with ISPs to provision native IPv6 routes, and the growing share of IPv6‑capable devices accessing its platforms.

IPv4 address exhaustion has left IPv6 as the only viable path for continued internet growth. Google’s traffic share demonstrates that IPv6 is no longer a fringe technology for major content providers. The figure also gives competitors a concrete benchmark: reaching half of total traffic on IPv6 is now a realistic target for any organization with a global user base.

The shift has practical implications for network engineers and product teams. Existing IPv4‑only infrastructure must be upgraded or supplemented with dual‑stack solutions to avoid performance bottlenecks. Cloud and edge services that rely on Google’s APIs should verify IPv6 compatibility to maintain latency and reliability standards.

Overall, the 50% milestone signals that IPv6 adoption is moving from experimental to operational at scale, and that the industry must align its roadmaps accordingly.
