Why IPv6 Matters: How Alibaba’s Full‑Scale Adoption Will Transform Every Industry

Alibaba announced full deployment of IPv6 across its services, making apps like Taobao, Tmall, Youku, and Amap among the first domestic apps with IPv6.

As the first cloud provider in China to fully support IPv6, Alibaba Cloud offers an end‑to‑end IPv6 solution covering over 200 industry scenarios, with DNS IPv6 queries growing 600‑fold since June 2018.

IPv6 (Internet Protocol Version 6) is the next‑generation IP protocol designed by the IETF to replace IPv4, providing a vastly larger address space—enough to assign a unique address to every grain of sand.

China’s strategic plan aims for 200 million IPv6 users by the end of 2018 and over 500 million by 2020, targeting more than 50 % of internet users, with the goal of leading the world in IPv6 scale by 2025.

IPv4 address exhaustion, the rise of 5G, IoT, and cloud computing drive the urgent need for IPv6, enabling unlimited public addresses for massive IoT devices, smart homes, autonomous vehicles, and more.

IPv6 also enhances security: each device gets a unique, traceable address, making fraud and illicit activities harder to hide.

Overall, widespread IPv6 adoption will empower industries ranging from cloud services and smart cities to autonomous driving and digital economies.
