Blocking or Canceling Blocking of an IP Address or IP Address Range

Scenario

If an IP address, IAM user, or IP address range added as blocked object for an emergency policy needs to be blocked in other operation connections, you can block them in batches. If there is no need to block an IP address, IAM user, or IP address range for operation connections, you can cancel the blocking in batches.

This section describes how to block or cancel blocking of IP addresses or IP address ranges in multiple connections.

Limitations and Constraints

If an IP address or IP address range or an IAM user is added to the blacklist, CFW/WAF/VPC/IAM will block requests from that IP address without checking whether the requests are malicious.
