Google Reports IPv6 Hits 50% Usage Across Services, Matching IPv4 Levels

Google’s internal traffic dashboards show that the March 28 spike to exactly half of all requests arriving over IPv6 wasn’t a fluke—it’s the first time the world‑wide split between the old and new internet protocols has ever been even. The data, which Tom’s Hardware cites from Google’s own monitoring, marks a watershed moment for a protocol that has lingered in the shadows since its 1998 debut. “For a brief moment,” the site notes, “50 % of worldwide users accessed the service over an IPv6 connection,” a historic first that finally puts the newer stack on equal footing with IPv4.

The shift is more than a vanity metric; it eases the pressure on an IPv4 market that has been inflating like a bubble for years. After IANA exhausted its global pool in 2011 and RIPE NCC followed suit in 2019, the remaining four‑octet addresses have become a scarce commodity, trading at roughly $50 each in 2019 and prompting cloud providers to monetize them directly. Amazon, for instance, began charging $0.005 per hour for each IPv4 assignment in 2024, a price that nudged engineers toward IPv6 adoption. With Google now delivering half its traffic on the newer protocol, the incentive to hoard IPv4 addresses weakens, potentially cooling the secondary market that has turned entire address blocks into loan collateral.

Regional data backs up the global trend. APNIC reports that 43 % of the world’s internet users are already on IPv6, with Asia and the Americas inching closer to the 50 % mark. Cloudflare’s own measurements, which count actual packets rather than just address allocations, show 40 % of traffic flowing over IPv6—a figure that, while still shy of Google’s milestone, underscores a broader industry migration. The convergence of these numbers suggests that the “address‑scarcity pressure” highlighted by Tom’s Hardware is beginning to lift, as more networks and devices shed their reliance on the dwindling IPv4 space.

The technical advantages of IPv6 are now hard to ignore. Its 2¹²⁸‑address space eliminates the need for NAT tricks and the costly juggling of address blocks that have plagued operators for a decade. Yet adoption lagged because early implementations were seen as “headache‑inducing” and difficult to roll out, a perception that has faded as the cost of IPv4 climbs and the ecosystem matures. The Verge‑style rhythm of today’s internet—smartphones, IoT gadgets, and cloud workloads—demands the scalability IPv6 offers, and Google’s traffic parity is a clear signal that the industry is finally answering that call.

What this means for end users is subtle but significant. Most people won’t notice a difference in speed or reliability, but the behind‑the‑scenes shift reduces the likelihood of throttling or outages caused by IPv4 exhaustion. It also opens the door for more innovative services that rely on the vast address pool, such as massive sensor networks and next‑generation edge computing. As Google’s traffic graphs level out, the internet’s backbone is quietly being rewired, and the once‑theoretical promise of a limitless address space is becoming everyday reality.
