value
When a domain name (such as www.aliyun.com) is resolved, if the resolved IP address or CNAME is not in the DNS hijacking white list, the user will fail to access or return a target IP address that is not Aliyun. If the IP or CNAME in the resolution result is in the DNS white list, it will be determined that DNS hijacking has not occurred. Fill in the format: Domain name: matching rules. Match rules support IP, IP wildcard, subnet mask, and CNAME. Multiple match rules can be filled in. Multiple match rules are separated by vertical bars (|). For example, www.aliyun.com:203.0.3.55 | 203.3.44.67 indicates that all other IP addresses under the www.aliyun.com domain except 203.0.3.55 and 203.3.44.67 are hijacked.
