CreateSubnet

CreateSubnet

1. API Description

This API is used to create a subnet under a VPC.

Note

• The quantity of subnets you can create under one VPC is limited. The IP range of the subnet under a VPC should be a subset of the VPC IP range.

• IP ranges of subnets under the same VPC cannot be overlapped.

• Call DescribeSubnetRegions to query regions supporting subnet creation.

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
vpcId	Yes	String	VPC ID.
regionId	Yes	String	Region ID.
stackType	Yes	String	Subnet IP stack type. The optional values are as follows: IPv4, IPv4_IPv6, IPv6
ipv6Type	No	String	Subnet IPv6 type. The optional values are as follows: Public, Private
name	Yes	String	Subnet name to be displayed. This parameter must start and end with a number or a letter, containing 2 to 63 characters. Only letters, numbers, - and periods (.) are supported.
cidrBlock	Yes	String	CIDR block of the subnet.

3. Output Parameters
