	Trace your internet connection

Solution Traceroute is often used for network troubleshooting. By showing a list of routers traversed, it allows the user to identify the path taken to reach a particular destination on the network. This can help identify routing problems or firewalls that may be blocking access to a site.

Traceroute is a utility that checks how many "hops" (transfers through other computers on a network) it takes for your computer to contact another computer(i.e. our servers).

To access the utility:

Any Windows: Press "Win key + R", type cmd, and then press Enter.�

Windows 7 or Vista: From the Start menu, in the search field, type cmd , and then press Enter.

Previous versions of Windows (XP, 2000, etc): From the Start menu, select Run... . In the "Open:" box, type: cmd and then press Enter.

At the command prompt, enter:

tracert 95.211.114.163 > 95.211.114.163.txt

then click Enter. It may take a while before the process finishes (up to a few minutes) The next line down you will see the flashing cursor.

Example output is as follows:

C:\Users\111pix>tracert 95.211.114.163 > 163.txt

Please do the above process for the following IP adresses:

tracert 95.211.114.163 > 95.211.114.163.txt
tracerе 95.211.114.171 > 95.211.114.171.txt
tracert 69.55.48.198 > 69.55.48.198.txt

Once you finished please type the following:

explorer . [explorer Space Dot] and click Enter.
e.g. C:\Users\111pix>explorer .

This will open a folder with the result files so now you can open each document individually and Copy & Paste the results onto email. You will see actual results inside each file. With a good connection you shouldn't have a delay of more than 100ms from a server. For example, if you enter tracert www.indiana.edu you should see something similar to the following:

1 <10 ms <10 ms <10 ms 168.91.41.1
2 10 ms 20 ms 20 ms indy-bloomington-s4-6.ivy.tec.in.us [168.91.9.129]
3 10 ms 10 ms 20 ms akicita-lena.ivy.tec.in.us [168.91.1.4]
4 20 ms 30 ms 30 ms indnet.ivy.tec.in.us [168.91.1.130]
5 71 ms 40 ms 50 ms ind-s1-0-7-T1.ind.net [157.91.8.62]
6 80 ms 40 ms 40 ms serverfarm-atm0.ind.net [199.8.76.231]
7 60 ms 90 ms 80 ms iupui-atm6-0-100.ind.net [157.91.9.78]
8 50 ms 40 ms 90 ms indy-dmz.atm.iupui.edu [134.68.15.103]
9 * * * Request timed out.
10 40 ms 70 ms 90 ms wcc6-gw.ucs.indiana.edu [129.79.8.6]
11 40 ms 50 ms viator.ucs.indiana.edu [129.79.78.8]

The first column, the hop count, represents the number of stops your information has made along the route to attempt to contact the other computer. The second column represents the delay between your computer asks server for a reply and the server replies. The above example shows that a computer user on ivy.tec ran a traceroute to www.indiana.edu. On the fifth hop, the request left the Ivy Tech network and went to the ind.net network. On the eighth hop, the request went to the iupui.edu network. Finally, on the tenth hop, the request found its way to the indiana.edu network. Since there is a "Request timed out" message on the ninth hop, you might guess that there could be some problem between the iupui.edu network and the indiana.edu network. If you were seeing other problems, such as the web page at http://www.indiana.edu/ loading slowly, this could indicate the location of the problem. A network technician will need to analyze the problem further. Please make sure that all your hops have less than 100 ms delay and no request timeouts. Otherwise you need to contact your ISP with these tracing results to solve network problem.
