summary: Create Secondary Subnet
description: Creates a secondary subnet in a secondary network. A secondary subnet CIDR block must not overlap with the CIDR block of an existing secondary subnet in the secondary network. After you create a secondary subnet, you can't change its CIDR block. The allowed size for a secondary subnet CIDR block is between /28 netmask (16 IP addresses) and /12 netmask (1,048,576 IP addresses). Amazon reserves the first four IP addresses and the last IP address in each secondary subnet for internal use.
