| VPC | `aliyun vpc allocate-eip-address` | AllocateEipAddress | Allocate EIP |
| VPC | `aliyun vpc describe-eip-addresses` | DescribeEipAddresses | Query EIP list |
| VPC | `aliyun vpc associate-eip-address` | AssociateEipAddress | Associate EIP (for ECS/NAT) |
| VPC | `aliyun vpc unassociate-eip-address` | UnassociateEipAddress | Disassociate EIP |
| VPC | `aliyun vpc release-eip-address` | ReleaseEipAddress | Release EIP |

| ECS | `aliyun ecs delete-security-group` | DeleteSecurityGroup | Delete Security Group |
| ECS | `aliyun ecs run-instances` | RunInstances | Create ECS instance |
| ECS | `aliyun ecs describe-instances` | DescribeInstances | Query ECS instances |
| ECS | `aliyun ecs delete-instance` | DeleteInstance | Delete ECS instance |
| ALB | `aliyun alb create-load-balancer` | CreateLoadBalancer | Create ALB |
| ALB | `aliyun alb get-load-balancer-attribute` | GetLoadBalancerAttribute | Query ALB attributes |
| ALB | `aliyun alb delete-load-balancer` | DeleteLoadBalancer | Delete ALB |
| ALB | `aliyun alb update-load-balancer-address-type-config` | UpdateLoadBalancerAddressTypeConfig | Update ALB address type (bindng/unbind EIP) |

## EIP bindng Resource Type Mapping

| Resource Type | InstanceType Value | InstanceId Example | bindng Method |
|---------------|-------------------|-------------------|----------------|
| ECS Instance | `EcsInstance` | `i-bp123xxx` | `associate-eip-address` |
| NAT Gateway | `Nat` | `ngw-xyz789` | `associate-eip-address` |
| ALB Instance | N/A | `alb-abc123` | `update-load-balancer-address-type-config` |

> **Note**: ALB uses `update-load-balancer-address-type-config` API to bindng/unbind EIP, not `associate-eip-address`.
