    Why is traceroute failing at 172.16.7.2


    I tried to traceroute from my home PC to my server which is located on another continent and it timed out. Also i was unable to use that server as my web browser proxy, it timeouts.

    But i also tried traceroute to google IP and it worked.

    My question is what is the cause and why it timeouted at IP 172.16.7.2?

    RFC1918. The IP Address you are pinging/tracerouting to is a non-routed IP Address.

    sometimes traceroute goes without issues and sometimes it timeout as in the screenshot i provided..

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Where is your server located, and where are you located. With recent earthquakes a lot of undersea cables have been damaged, and the results have been a lot of this sort of problem.
    Sometimes, real fast is almost as good as real time.

    Central Europe - Germany, Austria, Poland, Romania, where? Post the output from traceroute here please. Thanks.

    Ok, traceroute shows over 60 hopes between here and there (here being near Chicago), and ping isn't getting through yet. I quit after 121 packets sent...

    Personally, I think that there are issues with one (or more) of the gateways between there and here. Contact your ISP's tech support team and see if they can trace it down better.
