Although China stood on the same starting line as other countries on IPv6 development and allotment, it is once again facing severe challenges.
According to statistics released by the Regional Internet Registry (RIR), China only has 11 of the 499 IPv6 addresses, accounting for 1.8% of the total. Most of the blocks it has are /32, far smaller than those applied for by other countries. This quota is even smaller when the global share is taken into consideration.
One reason for this slow start is China's overestimation of IPv4 's utility, and ignoring that of IPv6. With the future increase in demand, China is likely to face a serious IPv6 shortage.
