IPv6 Adoption Grows, But Home Networks Still Lag Behind
Key points
- Half of Google users connect via IPv6.
- IPv4 addresses ran out in 2011.
- IPv6 offers 340 undecillion addresses.
- Carrier-grade NAT can hinder online gaming.
IPv6 Adoption and Home Network Status
Approximately half of Google's user base currently accesses its services using IPv6. Despite this, many home routers continue to operate with IPv6 switched off, even though most modern routers support it alongside IPv4 in a dual-stack configuration. IPv6 does not inherently improve Wi-Fi speed.
The Depletion of IPv4 Addresses
IPv4, introduced in 1981, utilized 32-bit addresses, providing approximately 4.3 billion unique addresses. These addresses were fully allocated by 2011, with North America's supply exhausting in September 2015. This depletion necessitated the transition to a new addressing system.
Network Address Translation (NAT) Limitations
To manage the IPv4 shortage, home routers employ Network Address Translation (NAT), allowing multiple devices to share a single public IP address. Internet service providers (ISPs) also use carrier-grade NAT, which places groups of customers behind shared addresses. This additional layer of NAT can create connectivity issues for certain applications, such as peer-to-peer online gaming, where direct connections are required.
The Scale of IPv6
IPv6 was standardized in 1995 and uses 128-bit addresses, providing an immense number of unique addresses—approximately 340 undecillion (10^36). This vast address space eliminates the scarcity issues faced by IPv4, allowing every device globally to have its own unique IP address.

Reporting from
Half of Google's users now connect via IPv6, but many home routers still have it disabled. IPv4 addresses ran out in 2011, leading to the adoption of IPv6, which offers a significantly larger address space and avoids issues caused by carrier-grade Network Address Translation (NAT).
