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. Additionally, IPv4 uses a system of public versus private addressing that determines how hosts and networks can connect over the Internet. Understanding the features of these addressing schemes will be essential to your career in network support.

The core function of IP is to facilitate the creation of a group of logically distinct but interconnected networks, referred to as an internetwork. This means that some packets addressed to hosts on remote networks must be forwarded via one or more of the intermediate systems that establish paths between networks.
In this topic, you will identify the basic principles by which IPv4 distinguishes local and remote hosts and networks.
