Google Cloud publishes 1,151 IP ranges.
Short answer
Google Cloud publishes cloud.json: the external address ranges available to Google Cloud customers, with the region (scope) each one is used in.
What it’s for
Use it to recognise traffic from Compute Engine and other Google Cloud resources. Google’s own services use the separate goog.json list.
