How do I run a traceroute?

Performing a Traceroute

Traceroute is a common utility that determines the network route data is taking to a destination. It is available on all major Operating Systems.

CloudFlare support will frequently ask for the output of a traceroute (you must have CloudFlare turned on) if you are experiencing connectivity issues. Please follow the instructions appropriate for your computer below:


  1. Open the Start menu
  2. Click on Run
  3. Type cmd and then press the OK button to open a command prompt
  4. At the prompt, type tracert and press the Enter key
  5. To copy the output, right-click anywhere in the window and select Mark. You can press Enter to copy all of the output, or select the text you want to copy and then right-click with your mouse. Paste the copied text by hitting CTRL + V.

Note: To traceroute IPv6 you would simply execute :  tracert -6 'your_domain_url'


  1. Open a terminal window
  2. Type traceroute at the prompt and press the Enter key

Note: To traceroute IPv6 you would simply execute traceroute6

Mac OS

  2. Type the domain or IP address in the appropriate input field and press Trace. You can also open a terminal window and use the same instructions as you would for performing a traceroute in Linux.
