Last updated: 2020-08-28 15:02:27


    This is a legacy API which has been hidden and will no longer be updated. We recommend using the new VPC API 3.0 which is standardized and faster.

    1. API Description

    This API (UnassignPrivateIpAddresses) is used to return the private IP of ENI.
    Domain for API request:

    If an auxiliary private IP on the ENI is returned, the API will automatically dissociate it from the elastic public IP. The primary auxiliary private IP on the ENI cannot be returned.

    2. Input Parameters

    The following request parameter list only provides API request parameters. Common request parameters need to be added when the API is called. For more information, refer to Common Request Parameters. The Action field for this API is UnassignPrivateIpAddresses.
