1. API Description
Domain name for API request: vpc.tencentcloudapi.com.
This API (AssignPrivateIpAddresses) is used to apply for private IPs for ENI.
- An ENI can be bound with a limited number of IPs.
- You can specify the private IP you want to apply for. It cannot be the primary IP, which already exists and cannot be modified. The private IP must in the same subnet as the ENI, and cannot be in use.
- You can apply for more than one secondary private IPs for the ENI. The API will return the specified number of secondary private IPs in the subnet IP address range of the ENI.
A maximum of 100 requests can be initiated per second for this API.
Note: This API supports Finance regions. Since Finance regions and non-Finance regions are isolated and not interconnected. If the common parameter Region is a Finance region (such as ap-shanghai-fsi), you need to specify a domain name containing the Finance region that should be identical to the value of Region field, for example: vpc.ap-shanghai-fsi.tencentcloudapi.com.
