Anti-DDoS supports configuring IP blocklist and allowlist to block or allow source IPs accessing the Anti-DDoS services, restricting the users accessing your business resources. If the accessing traffic exceeds the cleansing threshold, the allowed IPs will be allowed to access resources without being filtered by any protection policy; while the access requests from the blocked IPs will be directly denied.

Prerequisites

You have purchased an Anti-DDoS Advanced instance and set the object to protect.

Note：

The IP blocklist/allowlist will take effect after being created.

• The allowed IPs will be allowed to access resources without being filtered by any protection policy.
• The access requests from the blocked IPs will be directly denied.

Directions

1. Log in to the Anti-DDoS console and select Anti-DDoS Advanced (New) > Configurations on the left sidebar. Open the DDoS Protection tab.
2. Select an Anti-DDoS Advanced instance ID in the list on the left, such as "bgpip-xxxxxx".
   
3. Click Set in the "IP blocklist/allowlist" section.
   
4. Click Create. In the pop-up window, tick Blocklist or Allowlist as the type, enter the target IP, and click OK.
   
5. (Optional) After the rule is created, it is added to the rule list. To delete it, click Delete in the "Operation" column on the right.
