1. API Description

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

This API is used to create subnets in batches.

  • You must create a VPC instance before creating a subnet.
  • After the subnet is successfully created, its IP address range cannot be modified. The subnet IP address range must fall within the VPC IP address range. They can be the same if the VPC has only one subnet. We recommend that you keep the subnet IP address range within the VPC IP address range to reserve IP address ranges for other subnets.
  • The subnet mask of the smallest IP address range that can be created is 28 (16 IP addresses), and that of the largest IP address range is 16 (65,536 IP addresses).
  • IP address ranges of different subnets cannot overlap with each other within the same VPC instance.
  • A subnet is automatically associated with the default route table once created.
  • You can bind a tag when creating a subnet. The tag list in the response indicates the tags that have been successfully added.

A maximum of 20 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: CreateSubnets.
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.
VpcId Yes String The ID of the VPC instance, such as vpc-6v2ht8q5.
