IP blocked : I need to whitelist the webpagetest bots ip


We have a protection system which block somes IP. So, I can’t test our website. It seems that your IP is blocked by our system.

We have tried to isolate your IP(s) to find them in the server logs. But without success, “you” have many IP maybe.

Does the list of IP exist ? I will able to whitelist them.



Most of the IP addresses are here: https://www.webpagetest.org/getTesters.php?f=html

The Dulles ones (which are listed as private) are from

And https://www.webpagetest.org/getTesters.php?f=json gets you a nice API to automate the task.
