Creates a virtual private cloud (VPC).

Descriptions

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

  • You can specify only one CIDR block for a VPC. The CIDR block must be 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, or their subnets, and the subnet mask must be 8 to 24 bits in length. The default CIDR block is 172.16.0.0/12.
  • After you create a VPC, you cannot modify its CIDR block.
  • Each VPC can use at most 60,000 private IP addresses. The quota cannot be increased.
  • 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.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

  • 10.0.0.0/8.
  • 192.168.0.0/16.
Ipv6CidrBlock String No 2408:XXXX:0:6a::/56

The IPv6 CIDR block of the VPC.

EnableIpv6 Boolean No false

Specifies whether to enable the IPv6 CIDR block. Valid values:

  • false (default) disabled
  • true: enabled
VpcName String No abc

The name of the VPC.

The name must be 2 to 128 characters in length, and can contain digits, periods (.), underscores (_), and hyphens (-). It must start with a letter and cannot start with http:// or https://.

Description String No This is my first Vpc

The description of the VPC.

The description must be 2 to 256 characters in length. It must start with a letter and cannot start with http:// or https://.

ResourceGroupId String No rg-acfmxazb4ph6aiy****

The ID of the resource group.

DryRun Boolean No false

Specifies whether to precheck this request. Valid values:

  • true: sends a check request without creating a VPC. The system prechecks the required parameters, request format, and service limits. If the request fails the precheck, the corresponding error code is returned. If the request passes the precheck, the DryRunOperation error code is returned.
  • false: sends the request. This is the default value. If the request passes the precheck, a 2XX HTTP status code is returned and a VPC is created.
UserCidr String No 192.16.0.0/12

The user CIDR block. Separate multiple CIDR blocks with commas (,). At most three CIDR blocks are supported.

For more information, see What is a user CIDR block? in CIDR block FAQ.

ClientToken String No 123e4567-e89b-12d3-a456-426655440000

The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The ClientToken value must contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How can I ensure idempotence?

Ipv6Isp String No BGP

The Internet service provider (ISP) for IPv6 addresses of the VPC. Valid values:

  • BGP(default): Alibaba Cloud BGP IPv6
  • ChinaMobile: China Mobile (single line)
  • ChinaUnicom: China Unicom (single line)
