Operating Instructions In order to solve the problems of malicious IP theft and attack, CDN provides the function of configuring IP black and white lists Log in to the console ->CDN ->Domain name management ->Configuration ->Access control IP black and white list modification configuration - IP white list: When the IP address of the client that initiated the request matches the IP address or IP segment in the list, the access can normally return the requested content, and other requests can directly return 403.
- IP blacklist: When the IP address of the client that initiated the request matches the IP address or IP segment in the list, access directly returns 403, and other access can normally return the requested content.
- Support multiple IP or network segments input
- A network segment can be used to describe an IP segment, which means, for example, 127.0.0.1/24. 24 means that the first 24 bits of the subnet mask are valid bits, that is, the first 32 bits of the binary IP address are valid, and the last 8 bits represent the range of the network segment. So 127.0.0.1/24 indicates that the IP network segment range is 127.0.0.1~127.0.0.255. Currently, only "/8", "/16" and "/24" are supported
