// Creates a subnet in the specified VPC. For an IPv4 only subnet, specify an IPv4
// CIDR block. If the VPC has an IPv6 CIDR block, you can create an IPv6 only
// subnet or a dual stack subnet instead. For an IPv6 only subnet, specify an IPv6
// CIDR block. For a dual stack subnet, specify both an IPv4 CIDR block and an IPv6
// CIDR block. A subnet CIDR block must not overlap the CIDR block of an existing
// subnet in the VPC. After you create a subnet, you can't change its CIDR block.
// The allowed size for an IPv4 subnet is between a /28 netmask (16 IP addresses)
// and a /16 netmask (65,536 IP addresses). Amazon Web Services reserves both the
// first four and the last IPv4 address in each subnet's CIDR block. They're not
// available for your use. If you've associated an IPv6 CIDR block with your VPC,
// you can associate an IPv6 CIDR block with a subnet when you create it. If you
// add more than one subnet to a VPC, they're set up in a star topology with a
// logical router in the middle. When you stop an instance in a subnet, it retains
// its private IPv4 address. It's therefore possible to have a subnet with no
// running instances (they're all stopped), but no remaining IP addresses
// available. For more information, see Subnets (https://docs.aws.amazon.com/vpc/latest/userguide/configure-subnets.html)
// in the Amazon VPC User Guide.
