Creates a VPC with the specified CIDR blocks. For more information, see VPC CIDR blocks in the Amazon Virtual Private Cloud User Guide.

You can optionally request an IPv6 CIDR block for the VPC. You can request an Amazon-provided IPv6 CIDR block from Amazon's pool of IPv6 addresses, or an IPv6 CIDR block from an IPv6 address pool that you provisioned through bring your own IP addresses (BYOIP).

By default, each instance that you launch in the VPC has the default DHCP options, which include only a default DNS server that we provide (AmazonProvidedDNS). For more information, see DHCP option sets in the Amazon Virtual Private Cloud User Guide.

You can specify the instance tenancy value for the VPC when you create it. You can't change this value for the VPC after you create it. For more information, see Dedicated Instances in the Amazon Elastic Compute Cloud User Guide.
