The number of active IPv6 users in China has reached 608 million, and IPv6+ development has entered the second phase

On January 22nd, according to Fei Xiang News, China Unicom IPv6+ Innovative Practice and Scale Deployment Promotion Conference was held at the same time in Unicom's main venue and Xiong'an branch venue on January 20th. Wu Hequan, Director of the Expert Committee for IPv6 Scale-deployment and Academician of the Chinese Academy of Engineering, elaborated on the technical development direction of IPv6+ 1.0/2.0/3.0, which will play an important role in accelerating the innovative development of IPv6+ and advancing IPv6 scale-deployment. Data shows that as of December 2021, the number of active IPv6 users in China has reached 608 million, accounting for 60.11% of China's Internet users. In terms of traffic, the total IPv6 traffic of metro area network exceeded 44.77 Tbps, accounting for 9.38% of the total traffic of the whole network, mainly because the upgrade of home gateway did not keep up. From the perspective of IPv6 address ownership, China has applied for a total of 60,059 IPv6 address resources, ranking first in the world in terms of address resources. From the perspective of IPv6 autonomous system, the percentage of AS supporting IPv6 has increased steadily, with 6359 AS supporting IPv6; the percentage of AS supporting IPv6 is 77.95%, and more than 2/3 of the network has completed IPv6 transformation. According to academician Wu Hequan, some international organizations also gave data on IPv6 adoption rate or penetration rate among Internet users, including China. According to APNIC, by the end of 2021, the ratio of IPv6 subscribers to Internet users worldwide is 28.28%, and China is 37.65%, second only to Japan and India. According to Akamai, China's IPv6 adoption rate is 21.6%, an increase of nearly 20 times compared with the end of 2017, ranking 38th in the world. Wu also said, "At present, IPv6 + is being promoted in phases in China, and IPv6 + development has entered the second phase, continuously improving network capacity.
