    Virtual Private Cloud:CreateDefaultVpc

    Last Updated:Nov 13, 2024

    Creates a default VPC.

    Operation description

    Usage notes

    When you call this operation, take note of the following items:

    • After you create a default VPC, you cannot change its CIDR block. However, you can add secondary IPv4 CIDR blocks to it.

    • In each default VPC, cloud services can use a maximum of 60,000 private IP addresses. You cannot increase the quota.

    • After you create a default VPC, a vRouter and a route table are automatically created for the VPC.

    • At most three user CIDR blocks can be added to a VPC. If a user CIDR block includes another user CIDR block, the one with the shorter subnet mask takes effect. For example, if 10.0.0.0/8 and 10.1.0.0/16 are specified, only 10.0.0.0/8 takes effect.

    • CreateDefaultVpc is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeVpcAttribute operation to query the status of the task:

      • If the default VPC is in the Pending state, the VPC is being configured.
      • If the default VPC is in the Available state, the VPC is available.

    • You cannot repeatedly call the CreateDefaultVpc operation within a specific time period.

    • You can create only one default VPC in each region.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    RegionIdstringYes

    The ID of the region to which the default VPC belongs.

    You can call the DescribeRegions operation to query the most recent region list.

    		cn-hangzhou
    Ipv6CidrBlockstringNo

    The IPv6 CIDR block of the default VPC.

    Note When EnableIpv6 is set to true, this parameter is required.
    		2408:XXXX:346:b600::/56
    EnableIpv6booleanNo

    Specifies whether to enable IPv6. Valid values:

    • false (default)
    • true
    		false
    ResourceGroupIdstringNo

    The ID of the resource group.

    		rg-acfmystnjq4****
    ClientTokenstringNo

    The client token that is used to ensure the idempotence of the request.

    You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters.

    Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.
