Request for PageSpeed Insights IP addresses for whitelisting

[Есения Кондратьева]

We currently have an IP-based firewall configured on our website, and unfortunately, it is blocking the PageSpeed Insights tool from successfully analyzing our pages.

Could you please provide the list or range of IP addresses that PageSpeed Insights uses to perform its tests? We would like to add them to our whitelist so we can continue measuring our site's speed without interruptions.

[Barry Pollard]

We don't publish a fixed set of IP addresses for PageSpeed Insights and they are subject to change so it could be any of the IPs in the Google list:
https://knowledge.workspace.google.com/admin/security/obtain-google-ip-address-ranges

You can also run Lighthouse locally, or through DevTools to measure performance (though this will not be as sharable and will be subject to the the device's capabilities, network connection, and whatever else is running on the deice at the time).

Thanks,

Barry

I think this not possible due to securities issues from Google.

If you'd like to look for an alternative, I can recommend Calibre (https://calibreapp.com/) — you can scan and monitor a whole website, from a fixed IP address. 

You can read about the available test locations and Fixed IP settings here: https://calibreapp.com/docs/synthetic/test-agent
