Not long ago, a high-end forum on domain name service security was held in Beijing. Beijing DragonZN released China's first "Report on the Status of China's Domain Name Service and Security" (hereinafter referred to as the "Report"). The report pointed out that more than 50% of China's domain name servers are relatively unsafe, and 57% of key information systems face domain name resolution risks. This report has sounded the alarm for webmasters who rashly choose domain name registrars.
