Using these ranges

Region prefix lists are used to allowlist traffic from workloads in southcentralus, to route or geofence by cloud region, and to recognise Azure 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.

Azure ranges are shared between customer workloads and Microsoft-operated services. An address in a regional compute range is usually a customer virtual machine; Microsoft's own crawlers and mail systems have separate, verifiable identities.
