+# Path Of The Packets
+
+You can use `traceroute` to determine the network path packets follow from
+your machine to some host server. For instance, if I want to know path
+between my laptop (connected to airport wifi) and my website
+[joshbranchaud.com](http://joshbranchaud.com), I can run the following
+command:
+
+```
+$ traceroute joshbranchaud.com
