Google Reaches 50% IPv6 Milestone

Google has reached a significant milestone in its adoption of IPv6, with 50% of its services now using the protocol. This achievement is a major step forward in the transition from IPv4, which has been the standard for many years. The shift to IPv6 is important because it provides a much larger address space, which is necessary to support the growing number of devices connected to the internet. The milestone is also a good argument for why people need IPv6, as it can help to alleviate the pressure on the IPv4 address market. According to recent data, the IPv6 protocol is in use by 43% of the world, with Asia and the Americas inching ever close to the 50% mark.

## What happened Google's tracking graph shows that for a brief moment in time on March 28, 50% of worldwide users accessed the service over an IPv6 connection, marking a historic first. The IPv6 protocol was designed in 1998 as a replacement for IPv4 and its limited number of addresses. Despite initial concerns about the complexity of implementing IPv6, the protocol has gained traction over time, with many major content providers and CDNs deploying it. The highest per-annum growth was around 5% if you treat the initial uptake curve as 2012-2018. The slope of that trend is also similar for both graphs where 10% per 3 years provides a good fit. The biggest content providers and CDNs have deployed IPv6, and their traffic usually accounts for the biggest chunk of the total internet traffic. ## Why it matters The shift to IPv6 is important because it provides a much larger address space, which is necessary to support the growing number of devices connected to the internet. The milestone is also a good argument for why people need IPv6, as it can help to alleviate the pressure on the IPv4 address market. The IPv4 space was exhausted with the big bang of internet-connected devices, with home computers slurping up addresses, quickly accompanied by internet-connected smartphones. In the latest decade or so, the rise of IoT devices and cloud computing ensured that any crumbs left were quickly taken. ## How to think about it The transition to IPv6 requires careful planning and implementation, as it can have significant impacts on existing infrastructure and services. It is essential to consider the potential benefits and challenges of IPv6 adoption and to develop strategies for mitigating any risks. This can involve assessing current infrastructure and services, identifying areas where IPv6 can be deployed, and developing plans for implementation and testing. ## FAQ
