In Figure 5-20, you can see that pinging my gateway is fast: less than 1 millisecond for the packet to travel from my computer to my router and back again. Next, ping a well-known Web site in the United States to see the average times taken. Remember that not all Web sites will respond to the ping command. In Figure 5-20, you can see that it took an average of 52 milliseconds for a packet to go from my computer to Google and back again. Also note that www.google.com has an IP address of 216.239.37.99. Now, ping a Web site outside the United States. In Figure 5-20, you can see that it took an average of 239 milliseconds for a packet to go from my computer to the City University of Hong Kong and back again. If you think about it, the Internet is amazingly fast. Deliverables 1. Ping your own default gateway. How many packets were returned? How long did it take for your default gateway to respond? 2.
