Tracert maps the way ttcp/ip packets takes from your computer to the destination.

Example:

C:\Documents and Settings\Mikael>tracert bbs.stardestroyer.net

Tracing route to stardestroyer.homelinux.org [65.95.144.170]
over a maximum of 30 hops:

Useful tool in IP networking

You have to type in an address to trace the route for.

It shows you the route from your computer to the server. It's kind of like a map.

No. You put in the URL or IP address of some other server. It will then attempt to contact it, listing the various routers it must go through on the way.

Let's take Faram's example:

Code: Select all

C:\Documents and Settings\Mikael>tracert bbs.stardestroyer.net

Tracing route to stardestroyer.homelinux.org [65.95.144.170]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  192.168.0.1
  2    15 ms     6 ms     6 ms  gw-n2fls32o962.telia.com []
  3     7 ms     7 ms     6 ms  10.0.112.1
  4     7 ms    17 ms     7 ms  hud-a12-feth3-1.se.telia.net [213.67.160.253]
  5     7 ms     8 ms     7 ms  hy-d6-geth8-1.se.telia.net [212.181.192.129]
  6    11 ms     7 ms     8 ms  fre-c2-pos10-1.se.telia.net [212.181.192.97]
  7     8 ms     7 ms    29 ms  fre-c1-pos4-2.se.telia.net [194.22.190.89]
  8     7 ms     7 ms     8 ms  s-b3-pos2-0.telia.net [213.248.67.61]
  9     7 ms     8 ms     7 ms  s-bb2-pos5-0-0.telia.net [213.248.66.9]
 10    16 ms    36 ms    19 ms  kbn-bb2-pos0-0-0.telia.net [213.248.65.29]
 11   107 ms   111 ms   130 ms  nyk-bb2-pos5-0-0.telia.net [213.248.64.34]

The first line (1) refers to his computer, in this case using a private class C IP address. The second line shows his home router and the name assigned to his UIP. The thirdl ine shows his ISP's router; lines 4-11 show the route data must take to reach Mike's webserver.

[blinkblink] Ermm... ok.. I was told to do a tracert thing when my internet goes out, so now I'm totally confused.. What happens if I don't know any other IPs?

Just type tracert bbs.stardestroyer.net.

If someone is asking you to perform a tracert because you've lost your connection, they're trying to diagnose where the problem is. Depending on where it gives time-out errors one can figure out what's the problem.

For example, if there's a timeout somewhere in a middle of similar-looking addresses, a router is probably down somewhere. If it manages to get close to the target, then the server might be down. If it times out near the beginning, your ISP may be having connection issues.
