The China Internet Network Information Center (CNNIC) has disclosed that China has only 27 blocks of registered IPv6 addresses, which is far less than those of developed countries like Germany, Japan and South Korea.

According to CNNIC, China's IPv6 address application ranks fourteenth in the world, and is 345 times less than that of Germany, which ranks first.

Furthermore, the allocation of IP addresses in China is unbalanced with half of them being taken by the developed eastern and coastal areas like Guangdong, Beijing, Jiangsu, Zhejiang, Shanghai and Shandong.
