What's this?

Traceroute tries to step through all hosts on a route by increasing the Time-To-Live of each package step by step. Unix traceroute usually sends UDP datagrams, Windows systems prefer ICMP. The response is an ICMP "Destination reached" anyway.
If you happen to get "* * *" in response, this hop refuses to send proper ICMP responses.
