Releases a specified elastic IP address (EIP).

Usage notes

Before you call this operation, take note of the following limits:

  • Before you release an EIP, make sure that the EIP meets the following requirements:
    • You can release only an EIP that is in the Available state.
    • You can release only a pay-as-you-go EIP. You cannot release a subscription EIP.
  • The ReleaseEipAddress operation is asynchronous. After you send the request, the system returns a request ID. However, the operation is still being performed in the system background. You can call the DescribeEipAddresses operation to query the status of an EIP:
    • If the EIP is in the Releasing state, the EIP is being released. In this state, you can only query the EIP and cannot perform other operations.
    • If you cannot query the EIP, the EIP is released.
  • You cannot repeatedly call the ReleaseEipAddress operation to release an EIP within the specified period of time.
