Preparing your VPC for the example deployment

A virtual private cloud (VPC) is the virtual network in which you deploy Amazon EC2 instances.

The first four IP addresses and the last IP address in each subnet CIDR block are reserved. You cannot assign these IP addresses to an instance.

For example, in a subnet with CIDR block 10.29.100.0/24, the following five IP addresses are reserved:

• 10.29.100.0: Network address.
• 10.29.100.1: Reserved by AWS for the VPC router.
• 10.29.100.2: Reserved by AWS for mapping to the Amazon-provided DNS.
• 10.29.100.3: Reserved by AWS for future use.
• 10.29.100.255: Network broadcast address.
  Note: AWS does not support broadcast in a VPC.

Begin by creating the VPC in which you deploy the NGFW instances.
