Sample Network Configuration

• IP: 12.34.56.78
• Netmask: 255.255.255.0
• Gateway: 12.34.56.1

Important Information

• In most cases, you should not need to adjust these files. Instances are normally configured using DHCP. You only really need to change these files if you are trying to enable additional IPs.
• Changing to the examples below will cause problems if you take a snapshot of an instance and restore it. We recommend reverting back to DHCP before taking a snapshot.
