As well as understanding the different types of routing algorithms, you must be able to install routing devices to an appropriate place in the network. This lesson will help you to understand the role of routers placed at the network edge or perimeter. On IPv4 networks, this role involves the use of Network Address Translation (NAT) to manage communications between public and private address schemes.

While some support scenarios require a top-to-bottom or bottom-to-top approach, in practical terms a lot of troubleshooting activity starts with the Network layer. Connectivity tests and configuration information can identify issues within this layer or inform your decision of whether to move up or down layers to pinpoint the cause of a problem.

Organizations with large networks need to divide those networks up into smaller segments to improve performance and security. A network segment is represented at the Network layer by a subnet.
