Using these ranges

Region prefix lists are used to allowlist traffic from workloads in ap-southeast-5, to route or geofence by cloud region, and to recognise AWS 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.

AWS ranges are tagged by region and service. An address inside an EC2 range is a customer-controlled virtual machine, so the owner of the traffic is the AWS customer, not Amazon; abuse reports go to AWS, which forwards them to the customer.
