Amazon Web Services uses 105 prefixes for EBS.
Short answer
Amazon Web Services lists these prefixes under “EBS”. Amazon Web Services publishes every public address range it uses in ip-ranges.json, tagged by region and by service (EC2, CloudFront, S3, Route 53 health checks and more). The AMAZON service covers all of them; the other tags are subsets.
