When you run Traceroute, it gives you a simple report back from each “hop” it takes on the journey. A report might look like this:
3 int1-s1-0.dlls.tx.verio.net (219.5.892.521) 1.810 ms 1.795 ms 1.828 ms
This report tells us three things:
It is the third “hop” between your computer and the destination.
The location of the third hop is a router with the IP adress of 219.5.892.521.
Also provided is the name of that router
The three “packets” of information sent to that router from the second hop each arrived between 1.7 and 1.9 milliseconds (a millisecond, or “ms,” is one-thousandth of a second. Anything under 5 ms indicates a good connection. Over 60 ms suggest problems with the network.
The elements of the report may be in a different order depending on the program used for the traceroute, but they will always contain this information.
