Qxd 12 10/15/03 9:22 AM Page 12 Chapter 1 • Cisco Technologies, Routers, and Switches IP IP is an unreliable, routable packet delivery protocol. All upper layer protocols use IP to send and receive packets. IP receives segments from the Transport layer, fragments them into packets, and passes them to the Network Access layer. The IP address is a logical address assigned to each node on a TCP/IP network. IP addressing is designed to allow routing of packets across internetworks. Since IP addresses are easy to change or spoof, they should not be relied upon to provide identification in untrusted environments.
