--
-- Creates a subnet in a specified VPC.
--
-- You must specify an IPv4 CIDR block for the subnet. After you create a
-- subnet, you can\'t change its CIDR block. The allowed block size is
-- between a \/16 netmask (65,536 IP addresses) and \/28 netmask (16 IP
-- addresses). The CIDR block must not overlap with the CIDR block of an
-- existing subnet in the VPC.
--
-- If you\'ve associated an IPv6 CIDR block with your VPC, you can create a
-- subnet with an IPv6 CIDR block that uses a \/64 prefix length.
--
-- Amazon Web Services reserves both the first four and the last IPv4
-- address in each subnet\'s CIDR block. They\'re not available for use.
--
-- 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 about subnets, see
-- <https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Subnets.html Your VPC and subnets>
-- in the /Amazon Virtual Private Cloud User Guide/.
