1. API Description

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

This API is used to apply for an IPv6 address for the ENI.

This API is completed asynchronously. If you need to query the execution result of an async task, please use the RequestId returned by this API to poll the DescribeVpcTaskResult API.

• The number of IPs bound with an ENI is limited. For more information, see ENI Use Limits.
• You can apply for a specified IPv6 address. Currently, the IPv6 address can only be used as a secondary IP, instead of the primary IP.
• The address must be an idle IP in the subnet to which the ENI belongs.
• When applying for one or more secondary IPv6 addresses for an ENI, the API will return the specified number of secondary IPv6 addresses in the subnet range where the ENI is located.

A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: vpc.ap-shanghai-fsi.tencentcloudapi.com

2. Input Parameters
