Queries the details about the assets that are within the current Alibaba Cloud account. The assets can be elastic IP addresses (EIPs). The assets can also be Elastic Compute Service (ECS) instances or Server Load Balancer (SLB) instances that are assigned public IP addresses.

Usage notes

You can call the DescribeInstance operation to query the details about the assets that are within the current Alibaba Cloud account by page. The details include the IDs and IP addresses of the assets, the basic protection threshold and traffic scrubbing threshold that are configured for the assets in Anti-DDoS Origin Basic, and whether the assets are associated with Anti-DDoS Origin Basic instances.

Limits

You can call this operation up to 200 times per second per account. If the number of the calls per second exceeds the limit, throttling is triggered. As a result, your business may be affected. We recommend that you take note of the limit when you call this operation.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
