Using these ranges

Region prefix lists are used to allowlist traffic from workloads in asia-southeast1, to route or geofence by cloud region, and to recognise Google Cloud infrastructure in logs. Prefixes move between regions and services over time, so refresh any allowlist regularly rather than hard-coding it. An address inside these ranges tells you which network hosts it, not who is renting it; check each address's profile for risk evidence.

A Google Cloud address belongs to a Google Cloud customer, not to Google itself. Google's own crawlers use separate ranges and reverse DNS names, so a request claiming to be Googlebot from a Google Cloud customer range is not genuine.
