Using these ranges

Region prefix lists are used to allowlist traffic from workloads in ap-tokyo-1, to route or geofence by cloud region, and to recognise Oracle 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.
