How can I open up my site to webpagetest

Hi

I have an internal website which I need to open up for testing on Webpagetest.org.
I don’t want search engines to index this site so I can’t make it open for all.
How do I open up the site just for Webpagetest.org?

Is Webpagetest.org IP(72.56.115.10) static?

Thanks,
Deepak

It depends on what test location you want to test from. Most of the agent IP’s are available from here: http://www.webpagetest.org/getTesters.php and most tend to be static but there are no guarantees.

The Dulles location will run all tests from 72.66.115.14 which is static and will not change.
