    Virtual Private Cloud:UnassociateEipAddress

    Last Updated:Aug 29, 2024

    Disassociates an elastic IP address (EIP) from a cloud resource.

    Operation description

    • UnassociateEipAddress is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeEipAddresses operation to query the status of the task.

      • If the EIP is in the Unassociating state, the EIP is being disassociated. In this state, you can only query the EIP and cannot perform other operations.
      • If the EIP is in the Available state, the EIP is disassociated.

    • You cannot repeatedly call the UnassociateEipAddress operation within the specified period of time.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    ForcebooleanNo

    Specifies whether to disassociate the EIP from a NAT gateway if a DNAT or SNAT entry is added to the NAT gateway. Valid values:

    • false (default)
    • true
    		false
    RegionIdstringNo

    The ID of the region to which the EIP belongs. You can call the DescribeRegions operation to query the most recent region list.

    AllocationIdstringYes

    The ID of the EIP that you want to disassociate.

    		eip-2zeerraiwb7uj6i0d****
    InstanceIdstringNo

    The ID of the instance from which you want to disassociate the EIP.

    		i-hp3akk9irtd69jad****
    InstanceTypestringNo

    The type of instance from which you want to disassociate the EIP. Valid values:

    • EcsInstance (default): an Elastic Compute Service (ECS) instance in a virtual private cloud (VPC)
    • SlbInstance: a Server Load Balancer (SLB) instance in a VPC
    • NetworkInterface: a secondary elastic network interface (ENI) in a VPC
    • Nat: a NAT gateway
    • HaVip: a high-availability virtual IP address (HAVIP)
    		EcsInstance
    PrivateIpAddressstringNo

    The private IP address of the ECS instance or the secondary ENI from which you want to disassociate the EIP.

    		192.XX.XX.2
    ClientTokenstringNo
