Why are many apps written to support ipv6?

As we all know, IPV4 addresses are exhausted, and the advantages of IPV6 are more addresses, smaller routing table and better security.

To answer this question, we should talk about the national level from two levels (this is the strategic deployment of the whole country and the country's response. There are 65,438+03 root servers in the world, 65,438+0 primary root servers in the United States and 65,438+02 secondary root servers (including 9 in the United States, 2 in Europe and 65,438+0 in Japan). In the past, there was no root server for IPV4 in China, and the United States controlled the whole network by controlling the root server, which posed a potential major threat to the network security of other countries.

In 20 16, the "snowman project" completed the installation of 25 IPV6 root servers in the United States, Japan, India, Russia, Germany, France and other countries 16, forming a new pattern of 13 original IPV4 root servers plus 25 IPV6 root servers, in order to establish multilateral, democratic and transparent international internet governance. China deployed four IPV6 root servers, including 1 primary root server and three secondary root servers, which broke the dilemma that there was no root server in China in the past.

The Ministry of Industry and Information Technology proposes to implement IPV6 plan from six aspects, including: end-to-end IPV6 transformation of real-time LTE network, accelerating IPV6 transformation of fixed network infrastructure, suggesting IPV6 transformation of application infrastructure, carrying out IPV6 transformation of government website and IPV6 application of industrial Internet, strengthening IPV6 network security and implementing supporting measures. At the end of the first quarter of 20 19, all basic telecommunications enterprises have completed IPV6 interworking between LTE networks and mobile internet application system servers ranked first 10 by other basic telecommunications enterprises.

At present, IPV6 interconnection of backbone network has been basically completed. Fixed terminals fully support IPV6. Newly produced fixed terminals such as home gateways, enterprise gateways and routers promote IPV6 support, and support IPV4/IPV6 dual stack by default. At the end of 20 18, Alibaba Cloud, Tencent Cloud, Jinshanyun, NetScience, Lanxun and Telian Technology completed the IPv6 transformation of the content distribution network (CDN).

At the user level (IPV6 has better network support), in principle, apps that support IPV6 have better adaptability to the next generation network and higher security performance. This user can't intuitively feel it, but with the deployment of larger and larger organizations, this advantage will gradually be realized.

At present, mainstream knowledge apps all support IPV6, which is not the orientation of APP Store, but for publicity. When you see this fine print, you will get a feedback: Our application has deployed IPV6 and responded to the call. In the future, more and more enterprises will take the initiative to mark.
