This figure repeats the illustration from the previous figure, however here the three computers are identified with letters (the bottom computer is designated A, the middle is B, and the top is C) and each port is given an IP address in addition to the previously established MAC address.

The IP address for the router is given as "IP: 222.222.222.221." The IP address for computer A is given as "IP: 222.222.222.222." The IP address for computer B is given as "IP: 222.222.222.223." And the IP address for computer C is given as "IP: 222.222.222.220."
