How to prove / recognize packet loss and where happens using traceroute/mtr?

i like using tracert or traceroute (Linux/Windows) or mtr on Linux

mtr is good for monitoring where packet loss happens and how much percentage of pacets was lost.

When there are three stars on some traceroute hop (* * *) it mesns that the server not responded to the UDP/TCP request, but it do not mean that the traffic do not go thru it if i understand properly.

Here is nice explanation how to recognize if packet loss is there:

"Packet loss is really not a loss unless it continues through the trace route."

Yes, there is relatively much of providers which restrict their gateways to send ICMP answers to you and your tracert output can look like that:


5 58 ms 64 ms 68 ms 217.150.44.14
6 * * * Timeout
7 77 ms 76 ms 77 ms 213.248.99.221


I'm personally hate that because I can't be sure that there is no packet loss at that hop!
