Summary

Self-study questions 1.Which organization owns the host with the IP address ? 2.Ping and trace the route from two different places, for example your home and your office, to Are the ping times the same? Are the routes the same? Explain the differences? 3.I pinged Google.com from my home and from my office. If you look at the IP addresses of the final hops, you will see that they are different. Can you explain that? 4.Which do you like better, the command-line ping program that comes with Windows or the window-based program that I wrote? Why? Give at least one advantage for each. 5.If you trace the route between two hosts at different times, will it always be the same? Explain your answer. 6.If you measure ping time between two hosts at different times, will it always be the same? Explain your answer.
