Traceroute - An operation of sending trace packets for determining information; traces the route of UDP packets for the local host to a remote host. Normally traceroute displays the time and location of the route taken to reach its destination computer.

Basically... a program that counts and displays information on the number hops to a destination.

Which platform/OS you are using?
For windows, firewall up a DOS prompt and type:
tracert yourdomain_or_ip
