Percentage of LinkedIn site pageviews over IPv6 over the last year
For China, the story is a bit different. China for years had an IPv6 deployment on their Academic and Research Network. The government announced in September 2016 that its plan was to reach 200 million users on IPv6 by the end of 2018 and 500 million by the end of 2020. According to 2018 stats, it is estimated that there are about 800 million internet users in China, so 200 million would be about 20% IPv6.
In July, at a Chinese industry conference, the various providers publicly committed to the plan: Telecom providers decided to start to deploy IPv6 on mobile LTE networks, while service providers like Baidu, Tencent, and Alibaba committed to having their services reachable over IP6.
Since July 2018, LinkedIn has seen serious growth of IPv6 in China, from about 1-2% to more than 5%. While our data is likely not comprehensive enough to extrapolate from these numbers how close China is to its target of 200M internet users, it’s clear that there is fast growth of IPv6 there. By the end of 2018, they reached 8% to 9%, from our point of view.
Several organizations measure IPv6 deployment, including APNIC, Google, Facebook, Akamai, and the Internet Society. We don’t necessarily see the exact same numbers, however, because we don’t have all the same users, nor do we use the same methodologies. But what all of the available data shows for IPv6 growth in the APAC region is that India and China are likely to very soon have a bigger deployment of IPv6 in terms of devices/users than in the USA, which is past the 50% IPv6 deployment rate for a total of about 300 million internet users.
We tend to track by the percentage of deployment of IPv6 vs IPv4, but we also need to be mindful of how many internet users these deployments represent. Deploying at this scale is not an easy task.
IPv6 deployment is all happening behind the scenes, but it is happening in several countries that are gaining market advantage, increasing opportunities, and removing tech debt as a result (more information available here). At LinkedIn, we are following this path by working to enable IPv6 everywhere.
Thanks to everyone at LinkedIn who’s worked on putting the site on IPv6, our network team, and the traffic and site speed team for tracking IPv6 performance.
