1.3.9 Lab: mapping the internet

Figure 15 Ping output

Figure 16 Tracert output

Would you like to see how long it takes for data to travel from your computer to a remote destination and back? In Figure 15, the ping command took an average of 20 milliseconds to receive a reply from the server at www.cisco.com.

Would you like to see the path that data travels to reach a destination? In Figure 16, the tracert command generated a path showing that data passed through seven intermediary devices on its way from source to destination.

Network administrators and technicians use ping and tracert to test network connectivity and resolve problems. To further explore these two utilities, download Lab - Mapping the internet.
