Subnet
A subnet is a range of IP addresses in the Virtual Private Cloud (VPC) that can be used to isolate different EC2 resources or ECS services from each other or from the Internet. Each subnet resides in one Availability Zone. Subnets enable you to group instances based on security and operational needs. To enable instances in a subnet to reach the Internet and AWS services, you must add an Internet gateway to the VPC and a route table with a route to the Internet to the subnet.
Example:
subnet-53993c24: 172.31.16.0/20
