The market's VPC will be 10.0.0.0/16, with four /24 subnets: public-a 10.0.1.0/24, public-b 10.0.2.0/24, private-a 10.0.11.0/24 and private-b 10.0.12.0/24.

1. Look at the default VPC's subnets for comparison:

   sh

   copy

   aws ec2 describe-subnets --query "Subnets[].[AvailabilityZone,CidrBlock,AvailableIpAddressCount]" --output table
