Package traceroute

Traces the route taken by packets over an IPv4/IPv6 network

http://traceroute.sourceforge.net

The traceroute utility displays the route used by IP packets on their
way to a specified network (or Internet) host. Traceroute displays
the IP number and host name (if possible) of the machines along the
route taken by the packets. Traceroute is used as a network debugging
tool. If you're having network connectivity problems, traceroute will
show you where the trouble is coming from along the route.

Install traceroute if you need a tool for diagnosing network connectivity
problems.
