Creates a virtual private cloud (VPC).
Operation description
When you call this operation, take note of the following items:
-
You can specify only one CIDR block for each VPC.
-
After you create a VPC, you cannot change its CIDR block. However, you can add secondary IPv4 CIDR blocks to the VPC.
-
In each VPC, cloud services can use a maximum of 60,000 private IP addresses. You cannot increase the quota.
-
After you create a VPC, a vRouter and a route table are automatically created.
-
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 both 10.0.0.0/8 and 10.1.0.0/16 are specified, only 10.0.0.0/8 takes effect.
-
CreateVpc 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 VPC is in the Creating state, the VPC is being created.
- If the VPC is in the Created state, the VPC is created.
-
You cannot repeatedly call the DeleteRouteEntry operation to create default VPCs within a specific time period. However, you can repeatedly call this operation to create custom VPCs within a specific time period.

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.

| false |
Description | string | No | The description of the VPC. The description must be 1 to 256 characters in length and cannot start with | This is my first Vpc |
ResourceGroupId | string | No | The ID of the resource group. For more information about resource groups, see What is a resource group? | rg-acfmxazb4ph6aiy**** |
Tag | array<object> | No | The tag of the resource. | |
object | No | |||
Key | string | No | The key of tag N to add to the resource. You can specify at most 20 tag keys. The tag key cannot be an empty string. The tag key can be at most 128 characters in length. It cannot start with | FinanceDept |

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.
