is a commandline program that let's you follow the route of data packets as they travel from your IP address to the destination website. It's interesting because it reveals how your data travels through the physical world from server to server. It presents you with a breadcrumb trail you can follow.

Syntax Example
Only wait 3 seconds (instead of 5), only send out 1 query to each hop (instead of 3), limit the maximum number of hops to 16 before giving up (instead of 30) with the final host
