Path Analysis on Windows with pathping

Pathping is one of two network utilities I am aware of that produces network path-loss statistics. The other one is mtr which is available for both Windows and Linux. The two utilities are very similar, and here we’ll talk about pathping.

Pathping is developed and maintained by Microsoft, and it’s built into Windows. As the name implies, it’s a combination of tracepath (or traceroute) and ping. Both are based on ICMP packets. Tracerpath gives you the hop-by-hop information between two hosts. Ping gives you statistics when you send ICMP requests to a specific host. Pathping gives you the hop-by-hop information as well as statistics for each hop.


Pathping is preinstalled on Windows. I think this is a significant difference with mtr, that you’d need to compile under Cygwin, which is kind of a hassle. 

Here is the output of the help menu:

netbeez> pathping --help
--help is not a valid command option.

Usage: pathping [-g host-list] [-h maximum_hops] [-i address] [-n]
                [-p period] [-q num_queries] [-w timeout]
                [-4] [-6] target_name

    -g host-list     Loose source route along host-list.
    -h maximum_hops  Maximum number of hops to search for target.
    -i address       Use the specified source address.
    -n               Do not resolve addresses to hostnames.
    -p period        Wait period milliseconds between pings.
    -q num_queries   Number of queries per hop.
    -w timeout       Wait timeout milliseconds for each reply.
    -4               Force using IPv4.
    -6               Force using IPv6.

The options are pretty self explanatory.

Another significant different with mtr is that mtr is more feature rich if we judge from mtr’s available options:

netbeez> mtr.exe --help

 -b, --show-ips             show IP numbers and host names
 -o, --order FIELDS         select output fields
 -y, --ipinfo NUMBER        select IP information in output
 -z, --aslookup             display AS number
 -h, --help                 display this help and exit
 -v, --version              output version information and exit

A more rigorous comparison between the two might be a topic for another blog post…

Let’s look at an example of a pathping run:

netbeez> pathping

Tracing route to []
over a maximum of 30 hops:
  0  host.docker.internal []
  3     * []
  5 []
  6 []

Trace complete.

Pathping first runs a tracepath to get the hop-by-hop IP information between my laptop and Then for each hop, it sends 100 packets with 250 milliseconds interval to calculate statistics. This amounts to 25 seconds per hop and a total of 275 seconds for 11 hops. As you can see, it might take a while for pathping to finish its run, but all these parameters are configurable (-p for period and -q for number of queries per hop), as you can see from the options in the help menu.

As you can see for each hop, you have statistics on latency and on how many packets were dropped out of the 100 that were sent. This can be very useful when troubleshooting performance issues, and can help identify specific hops along your route that might be causing the overall issue.

All in all, I think pathping is a very useful tool, it comes for free on Windows, and it’s on par with its Linux equivalent mtr.
