Amazon AWS Default Virtual Private Cloud (VPC)

Newer Amazon AWS accounts (since December 4, 2013) include a default VPC, which mostly emulates the behavior of EC2-Classic networking for backward compatibility.

Instances in the default VPC are given public addresses and a route to the Internet by default. You can also create your own VPC.

Instances in a user-created VPC do not receive a public IP address or a route to the Internet by default, but are configurable.

Both default VPCs and user-defined VPCs can operate securely using features like security groups.
