In these sample files, most of the packet loss seems to be coming from hop #3. However, I'd highly recommend trying to trace directly to the IP address of hop #2 - the packet loss that's showing on hop #3 might be starting there.

You can compare the data from a direct trace to hop #2 and a direct trace to hop #3 to see where the packet loss really is starting.

If you're unable to get results from hop #2, I'd contact your ISP and tell them you're trying to consistently test ICMP Echo Replies from that device to gauge the level of packet loss. Ask them what port and protocol you need to configure to get a response from it. See Named Configurations for more info on this. (or, you can scan the IP with Nmap to find out for yourself).

Let me know if you have any other questions!
