1. API Description

Domain name for API request: vpc.intl.tencentcloudapi.com.

This API is used to apply for private IPs for an ENI.

  • An ENI can only be bound with a limited number of IP addresses. For more information about resource limits, see ENI Use Limits.
  • You can apply for a specified private IP. It cannot be a primary IP because the primary IP already exists and cannot be modified. The private IP address must be an idle IP in the subnet to which the ENI belongs.
  • You can apply for more than one secondary private IP on the ENI. The API will return the specified number of secondary private IPs in the subnet IP range.

    Note:

    This API is async. You can call the DescribeVpcTaskResult API to query the task result. When the task is completed, you can continue other tasks.

A maximum of 100 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name Required Type Description
Action Yes String Common Params. The value used for this API: AssignPrivateIpAddresses.
Version Yes String Common Params. The value used for this API: 2017-03-12.
Region Yes String Common Params. For more information, please see the list of regions supported by the product.
NetworkInterfaceId Yes String The ID of the ENI instance, such as eni-m6dyj72l.
PrivateIpAddresses.N No Array of PrivateIpAddressSpecification The information on private IP addresses, of which you can specify a maximum of 10 at a time. You should provide either this parameter or SecondaryPrivateIpAddressCount, or both.
SecondaryPrivateIpAddressCount No Integer The number of newly-applied private IP addresses. You should provide either this parameter or PrivateIpAddresses, or both. The total number of private IP addresses cannot exceed the quota. For more information, seeENI Use Limits.
QosLevel No String IP service level. It is used together with SecondaryPrivateIpAddressCount. Values: PT(Gold),AU(Silver),AG `(Bronze) and DEFAULT (Default).
ClientToken No String Idempotency token used to ensure request idempotency. This string is generated by the client and must be unique across different requests, with a maximum length of 64 ASCII characters. If this parameter is not specified, request idempotency cannot be guaranteed.

3. Output Parameters

Parameter Name Type Description
PrivateIpAddressSet Array of PrivateIpAddressSpecification The detailed information of the Private IP.
RequestId String The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.

4. Example

Example1 Applying for a private IP for an ENI

This example shows you how to apply for an ENI.

Input Example

POST / HTTP/1.1
Host: vpc.intl.tencentcloudapi.com
Content-Type: application/json
X-TC-Action: AssignPrivateIpAddresses
<Common request parameters>

    "Response": {
        "PrivateIpAddressSet": [
            {
                "PrivateIpAddress": "172.16.32.237"
            },
            {
                "PrivateIpAddress": "172.16.32.84"
            }
        ],
        "RequestId": "f23d1450-ed00-4442-98d4-be409e625e6c"
    }
}
