Reverse Traceroute Network Diagnostic Utility
Worried that your Internet traffic is taking an unnecessarily circuitous path
to you, ruining your performance (forcing you to wait too long when you
request webpages, or causing "life" threatening lags in your favorite games)?
Suspicious about what networks or countries might handle your traffic along
its journey? Want to know if your provider is getting you the performance you
are paying for? Just curious to see where data is coming from? For these
questions and more, our new reverse traceroute system is just the tool you
need! It allows you to measure the path from any destination back to you.
This webpage allows you to demo our new system. Select a test source from the
drop-down list (perhaps the one nearest you), enter the destination of your
choice, enter your email address (feel free to use a service like mailinator
to preserve anonymity), and then launch the measurement. We will
email you the result shortly. If you know the path (for instance, if you are
testing using a "destination" that you control), we invite you to copy and
paste the traceroute into the box below before you launch the measurement.
This information will help us improve the system. Note that, if you enter a
hostname (rather than IP address) for the destination, the resolution will
happen at University of Washington and may yield a different address than it
would at your location.
