In 2025, the first of the series of blogs is to emphasize the IPv6 state of the industry, consider best practices, and CISCO helps customers with customers’ products and services.
IPv6 complex history
IPv6: A protocol with a long and winding history, a protocol that can lead to all reactions from skepticism to curiosity, dismissal to openness, indifference and fear. In most cases, the first thing I hear is “never happen” or “What is happening in IPv6 anyway?” The first is very easy to solve Be accident. The progress may not be uniform in the world or market sectors, but data exists and can be surprising for many people.
Rising IPv6 traffic
The ratio of Google’s global IPv6 traffic has not exceeded 1% thresholds by 2013 for all of the user’s properties. Since then, it has reached about 48%at the end of 2024. 53%, France, Germany and India are 78%, 76%and 72%, respectively. As of 2022, Akamai saw 52% of US traffic when IPv6 and Facebook saw more than 61 percent in the United States. Nevertheless, when I dig into the data, I learned that the residential and mobile sectors led the numerous numbers that were covered by companies and public sectors.
Despite the initial promise, adoption delay
Considering this prominent level of adoption, it’s natural to wonder why it took so long to distribute a 30 -year -old protocol (!). Many people have memories of 1995-2015, when there were many conversations and over-advertising about IPv6, but nothing seemed to be realized. Network experts were trained, integrated into the test data, and were ordered by the previous government, but nothing was deployed.
At the same time, the industry has developed some lifetime extensions for IPv4 -CIDR, VLSM, NAT and RFC 1918 individual address spaces. It’s been a few years but decades. But as successful, they still couldn’t overcome the fact that 32 bits were not enough for today’s global Internet. We lacked a new public IPv4 address in the mid -2010s and still feel the results. The price has soared in the second market. The ISP had to distribute the transportation rating NAT and leave it to the shoulder of the operation problem. The company had to continue to reconstruct the network to build the last bit on each subnet. In addition, because other parts of the network began to use the same address block independently, many people had to deal with the overlapping pains of personal address space. This is forced to achieve more and more NATs. interior External connection, of course, communication.
Transition to IPv6
The good news is that there is a solution we are ready to go. I was just hibernated. But in some parts of the team, we needed a team effort to work well, but we needed to be struggling in other regions. Mobile and ground service providers have many networks that enable IPv6 (to run some single stack IPv6 cores), and large content providers have dual stacks to provide services to many potential customers as possible. I turned on and majored. Operating system suppliers have strengthened their support. Combined with the same development such as a happy eye (algorithm built into most endpoints to try IPv6 first), the user fails quickly to the IPv4 without a noticeable delay. I start to see why adoption has increased significantly.
But more work is needed in the company. There are all middle boxes, software suites, monitoring and management tools, identity and policy products and other operations, and there is a problem that mobile and home users are not facing.
Government support and IPv6 are moving forward
Many governments around the world, including the United States, including the OMB M-21-07, have seen this and focuses more after this gap (1). They know that even if they are foreseen in the IPv6 -only future and clearly required in the short term, it is an indefinite situation to remain in a dual stack. This future not only overcomes address fatigue, but also offers new and interesting opportunities for the impossible architecture and operation in a limited IPv4 world. Although CISCO has been published a bit in this previous (2), (2), colleagues and I will use the rest of the 2025 to prepare a series of blogs that will help the journey. INFINITE) How to switch from address space, IPv4 to IPv6 exclusive, consideration of security and operation, the role of fabric and other architectural design, and how management and monitoring in the IPv6 world look. Keep watching!
