The world heavily relies on the internet for both personal and professional needs. Over the years, the number of internet users has significantly increased worldwide, resulting in a massive demand for digital connectivity. However, such digital infrastructure requires a considerable number of internet protocol addresses, which is where IPv6 becomes relevant. Recently, China, which has the largest internet population in the world, has implemented a new policy to promote large-scale IPv6 deployment and application.
2023 Work Arrangement for Further Promoting Large-scale IPv6 Deployment and Application
Recently, the Central Cyberspace Administration of China, the National Development and Reform Commission, and the Ministry of Industry and Information Technology jointly issued the “2023 Work Arrangement for Further Promoting Large-scale IPv6 Deployment and Application.” The policy document sets ambitious targets for promoting the deployment and application of IPv6.
Specific objectives laid out in the agreement are as follows
China aims to have 750 million active IPv6 users and 300 million Internet-of-Things (IoT) connections on IPv6 by the end of 2023. The policy further breaks down the objectives into increasing the number of IP protocol addresses and promoting the implementation of IPv6-enabled products such as servers, routers, and devices.
Driving factors for the push towards IPv6
The demand for digital connectivity is continuously rising, fueled by the growth of new technologies like 5G, IoT, and cloud computing. IPv6 has the capacity to address more than trillions of internet protocol addresses, whereas IPv4 only has a limited number. The world is running out of IPv4 addresses, and as more and more devices come online, the need for more addresses increases.
Benefits of IPv6 over IPv4
IPv6 is the enhanced version of IPv4 and comes with numerous benefits. The carrying capacity and service quality of IPv6 is better than IPv4. IPv6 also offers better security features, making it harder for cybercriminals to intercept and steal data.
Concerns regarding IPv6+
IPv6+ is an enhanced version of IPv6 that caters to 5G and cloud variants and other technologies. One concern is that the granular control and enhanced capabilities of IPv6+ could be used by a government to restrict access to certain content or control the kind of communication users are allowed outside their country.
To effectively embrace new enhancements, the industry needs extensive interoperability and scalability testing. This testing is necessary to ensure that the new technologies do not hinder internet connectivity and that users can quickly switch to IPv6 without any complications.
Potential for government control and restriction with enhanced capabilities
As with any technology, there is also the risk of governments using it to limit users’ online freedom. Some of the granular control and enhanced capabilities of IPv6+ could be used to restrict access to certain content or monitor the communication activities of their citizens.
Factors Prolonging the Use of IPv6
The biggest factor prolonging the use of IPv6 is Network Address Translation (NAT). It allows private enterprise systems with private IP addresses to communicate with machines having public IP addresses. However, with more devices becoming operational, NAT becomes challenging since it is not scalable.
Market growth projections for IPv6
According to ResearchandMarkets.com, the global IPv6 market is expected to grow at a CAGR of 30.79% to reach $8.24 billion by 2027. The projected growth is due to the rapidly growing numbers of mobile and internet users worldwide and the increasing popularity of cloud computing.
The push towards IPv6 deployment and adoption by China is a step towards addressing the world’s increasing demand for digital connectivity. However, the enhancements and scalability of the technology must be harnessed to provide maximum benefit to users, while also ensuring that governments don’t use it to restrain online freedom. As China continues to push for IPv6 deployment, governments and organizations in other countries should embrace IPv6 and actively work to phase out IPv4.
