IP Addressing There are several related areas you must understand before you can make a router do useful things. You must understand: (1) how hosts and routers connect to physical media; (2) the potential relationships among physical media (and simulated physical media) to logical media; and (3) the conventions for IP and IPX addressing that involve setting up identifiers for points on logical media, and how to code these identifiers into routers. In this tutorial, the author begins with a review of topologies and then reviews IP addressing in a more binary and classless way, finally mapping into the decimal and classful way. Update: November 2002 The Study Questions have been revised and updated, including 22 brand new questions, covering classful and classless IP Addressing, as seen on the Cisco CCNA 607 exam.
