To start on Windows XP and getting to the command prompt how to go to “start”, “Accessories”, and then the “Command Prompt”
[pic]Here you can see when pinging 127.0.0.1, it went through all four cycles successful.
You can also see that the TTL or “Time to Live” is rated at 128. TTL is how long the packet can stay on the network before it is discarded.
Now we will ping “yahoo.com” and see what values we get.
You can see we had four successful cycles and an average of 52 for TTL. If there were problems with your network, the host site, or with you work station, you would see a “Request timed out” notification. If you see the notification on several attempts, either contact your network administrator of the problem, especially if you see the “Requested timed out” notification for every site you attempt. However, if it is only one particular site, you may want to try again in a couple of hours or the next day if the site is being updated or under construction.
Next we will ping 22.214.171.124 which is yahoo’s alternate address.
Again you can see that we get the same TTL of 52, the same as when we pinged “yahoo.com” to show both addresses for yahoo are working correctly.
Now we will ping yahoo’s alternate or IP address with the –a switch to see what resolution we get. You might see a different IP address in return, but usually not. It depends on the owner or site designer has configured the domain.
You can see that the address and site are still the same, as well as the TTL of 52. After you have experimented and seen in the diagrams of this paper, and you are using Windows Vista or XP, you can type “exit” as your next command to return to your normal screen.
