    276  2)  EC2 instances (servers) are dynamically assigned IP addresses when they are created. A public IP address is available for remote connections and a private IP address is created for internal communications (inside EC2). All network traffic between EC2 instances (inside the same availability zone of the same region) is free.  Traffic between resources in different regions is considered Internet traffic.  All network exchanges between GENI
