Creates a default VPC with a size <code>/16</code> IPv4 CIDR block and a default subnet in each Availability
Zone. For more information about the components of a default VPC, see <a
href="https://docs.aws.amazon.com/vpc/latest/userguide/default-vpc.html">Default VPCs</a> in the <i>Amazon VPC
User Guide</i>. You cannot specify the components of the default VPC yourself.

<p>
If you deleted your previous default VPC, you can create a default VPC. You cannot have more than one default VPC
per Region.
