OS X Traceroute Command: what is '*'
That means traceroute didn't get any responses to its probes. The way it works is that it sends out test packets set to expire after 1 hop, two hops, etc; then it listens for "sorry, but your packet expired before I could deliver it" and prints the addresses of the routers that sent those responses. The "*"s mean it didn't hear back.

You're getting all "*"s, which means that either there's no route to the destination, or there's a firewall blocking the probes and/or the responses, or something along those lines.
