Chapter Summary Continued
The Internet Protocol (IP) resides at the Internetwork Layer. It provides the logical address that can be passed through a router.
The IP address allows networks to be divided into subnetworks.
You can use the ping utility with IP and ICMP to diagnose and troubleshoot network connections at this layer.
You can use the Traceroute utility with IP to determine all the hops that a packet makes along its path to a remote TCP/IP host.
Address Resolution Protocol (ARP) and Reverse ARP (RARP) also reside in the Internetwork layer.
These protocols allow the TCP/IP host to resolve the IP address to a MAC address.
