traceroute
Traces the route taken by packets sent from the local router to the specified IP
address or domain name. A packet is sent for each hop in the route. The output lists
the IP addresses of the hops that returned packets.
Unless the -n option is specified, traceroute also attempts to look up the name of each
gateway in the route. If the DNS lookup is successful, the name is included in the
output message.
NOTE:
To terminate the traceroute before it ends, press control-c.
