CreateDefaultVpc - Virtual Private Cloud - Alibaba Cloud Documentation Center

Creates a default virtual private cloud (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

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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.

Operation	Access level	Resource type	Condition key	Associated operation
vpc:CreateDefaultVpc	Write	VPC acs:vpc:{#regionId}:{#accountId}:vpc/*	none	none

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	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
Ipv6CidrBlock	string	No	The IPv6 CIDR block of the default VPC. Note When EnableIpv6 is set to true, this parameter is required.	2408:XXXX:346:b600::/56
EnableIpv6	boolean	No	Specifies whether to enable IPv6. Valid values: false (default) true	false
ResourceGroupId	string	No	The ID of the resource group.	rg-acfmystnjq4****
ClientToken	string	No	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.	123e4567-e89b-12d3-a456-426655440000

Response parameters

Parameter	Type	Description	Example
	object	The ID of the default VPC.
VpcId	string	The ID of the default VPC.	vpc-bp15zckdt37pq72zv****
VRouterId	string	The vRouter ID that is automatically created by the system after you create a default VPC.	vrt-bp1lhl0taikrteen8****
RequestId	string	The request ID.	0ED8D006-F706-4D23-88ED-E11ED28DCAC0
RouteTableId	string	The route table ID that is automatically created by the system after you create a default VPC.	vtb-bp1q1uirugzb1x32m****
