Overview:

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.
