CreateVpc

The name of this action. Value: CreateVpc

The ID of the region to which the VPC belongs. To query the region ID, call DescribeRegions.

Optional. The IP address range of the VPC in CIDR block form. The following IP address ranges and their subnets can be used:

• 10.0.0.0/8
• 172.16.0.0/12 (default)
• 192.168.0.0/16

Optional. The client token that guarantees the idempotence of the request. The value of this parameter is generated by a client. It is unique among all requests and can contain a maximum of 64 ASCII characters.

Optional. The description of the VPC. The description must be 2 to 256 characters in length. It must start with a letter, but cannot start with http:// or https://.

Optional. Indicates whether to enable the IPv6 CIDR block. Valid values:

• false (default): Disable the IPv6 CIDR block.
• true: Enable the IPv6 CIDR block.

Optional. The IPv6 CIDR block of the VPC.

Optional. The ID of the resource group.

Optional. The customer-side CIDR block. Separate multiple CIDR blocks by using commas (,). Up to three CIDR blocks are supported.

A VPC uses 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 100.64.0.0/10, and the VPC CIDR block for intranet communication by default. If the ECS instances and Elastic IP Addresses (EIPs) that have access to the Internet (the ECS instances are assigned public IP addresses, or the ECS instances or their ENIs are associated with public IP addresses or configured with DNAT entries) visit the IP addresses outside the preceding CIDR blocks, the requests are forwarded to the Internet through the public IP addresses. If you want the requests (for example, from a VPC that is in a hybrid network environment built through VPN, Express Connect, or CEN) to be forwarded over the intranet according to a route table, you must set the destination CIDR blocks of the requests as the UserCidr of the corresponding ECS instance or Elastic Network Interface (ENI). After that, the requests from that VPC will be forwarded according to the route table, not through public IP addresses.

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