how to make webpagetest.org load a website from a different IP address

Question

I once received instructions from a web hosting support on how to use webpagetest.org to test a website from a different IP address to the one it is currently live at. This enables you to test the website on a different host to see if that host loads the website faster than the current host.

I've had a look at the Advanced Testing > Advanced tab, but I can't see how to achieve this.

Edit: from the Scripting help doc, there is a script command you can use:

setDnsName  www1.aol.com    www.aol.com
setDns  www.aol.com 127.0.0.1
setCookie   http://www.aol.com  zip=20166
navigate    http://www.aol.com

When I try just 1 line:

setDns  www.example.com.au  103.103.103.103

I receive error:

Invalid Script (make sure there is at least one navigate command and that the commands are tab-delimited). Please contact us if you need help with your test script.

Help appreciated.

Answer 1

I went to Advanced Testing > Script tab, and entered command:

setDns  www.example.com.au  103.103.103.103
navigate    www.example.com.au

and this worked for me
