Google measures 50% IPv6 adoption

Summary: An APNIC blog post dated 2026-04-28 covers Google's per-user IPv6 statistics crossing 50% for the first time, recorded 2026-04-23; APNIC Labs measured 42% global IPv6 capability on the same date. The post notes adoption varies sharply by economy, with India, Vietnam, and Saudi Arabia diverging from the global curve, and argues IPv4 already carries heavy NAT and CGNAT complexity, so there is no inherently simpler or cheaper IPv4-only path. The April article resurfaced as a 391-point HN thread on 2026-06-22.
Why it matters: Crossing 50% on Google's measurement marks IPv6 as the majority path for a large share of users, raising the cost of IPv6-incompatible network assumptions.
