Supported Network Segments

Cloud Native Anti-DDoS 2.0 outside the Chinese mainland can only protect the following premium BGP IP addresses:

49.0.236.0/22
49.0.234.0/23
49.0.233.0/24

After adding a premium BGP EIP to CNAD 2.0, it can defend against attacks originating from China but not those from outside China. The black hole threshold for a premium BGP EIP is low; when the number of attacks from outside China exceeds this threshold, the premium BGP EIP will be blocked. To defend against attacks from outside China, purchase an Anti-DDoS Service dedicated EIP and use it with CNAD 2.0.
