When testing CDNs from both Amazon EC2 (singapore) and various ISPs in Thailand, many CDNs fluctuate between Asian POPs. Usually I get Singapore, Hongkong or Japanese POPs. – Even Amazon cloudfront occasionally gets it wrong when testing from singapore EC2 which is probably a few racks away…
I would like to open the port for WebPageTest for our internal QA boxes. Looking at this page http://www.webpagetest.org/getTesters.php I am able to see some IP addresses, but some of them are using private addresses like 192.168.
So how do I know public IP addresses of test server for certain locations?
Yep, still accurate. Try with the desktop browsers first because those are a lot more stable and should give you something back (even if it is a page load error). Android is the next most reliable and iOS is by far the least.
All good with desktop browsers (chrome, IE11), the IP is whitelisted and I can get results back without entering auth info
No joy with android or iOS unfort, the screenshots still indicate that the authentication prompt is still firing on devices.
One trick I use to get the IP address of an agent is to make a request for http://whatismyip.akamai.com/ and look at the screen capture. This will show the IP of the agent as seen on the internet. You could then use this for white-listing purposes.
