The Chinese ccTLD has lost almost four million domain name registrations since it implemented Draconian identification requirements last December.
According to CNNIC, the .cn manager, there were 9.53 million domains registered at the end of February, compared to 12.28 million in January and 13.45 million in December.
That’s a loss of 3.9 million domains since the new registration requirements were introduced mid-December.
The bulk of the loss appears to have come from pure .cn names, which dropped from 8.61 million in December to 6.14 million in February.
The .com.cn namespace lost about half a million names over the same period. The rest of the drop-off came in lesser-used second-level domains such a .org.cn.
Since December 14, CNNIC has required all Chinese registrants to provide photo ID before they register a domain.
Recently, the registry has tried to enforce retroactive enforcement of this requirement, causing registrars including Go Daddy and Network Solutions to abandon the TLD altogether.
