ModifySubnetStackType

1. API Description

This API (ModifySubnetStackType) is used to modify the IP stack type of subnet under a global VPC.

Note

You can only change the IP stack type of subnet from IPv4 to IPv4_IPv6.

2. Input Parameters

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
subnetId	Yes	String	Subnet ID.
ipv6Type	Yes	IPv6Type	Subnet IPv6 type. The optional values are as follows: Public , Private
stackType	No	SubnetStackType	IP stack type of subnet. The optional values are as follows: IPv4_IPv6 Default value: IPv4_IPv6
ipv6CidrBlockId	No	String	ID of the public IPv6 CIDR block. This field can only be specified when ipv6Type is Public. If not specified, it will be allocated from the system's default IP pool.
ipv6MaskLength	No	Integer	The size of the IPv6 CIDR prefix assigned to the instance. This parameter must be used together with the ipv6CidrBlockId parameter. The default value is 96 if not explicitly provided. The minimum value must be greater than or equal to the prefix of the specified ipv6CidrBlockId, and the maximum value cannot exceed 96. Value range: [-, 96]

3. Output Parameters

Parameter Name	Type	Description
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
ipv6CidrBlock	String	IPv6 CIDR block of subnet.

4. Code Example
