Amazon AWS

Amazon Web Services routes much of its global cloud traffic through Autonomous System 16509, operated by Amazon.com, Inc. As the primary ASN of the world's largest cloud platform, it serves AWS regions and edge locations across every continent and supports millions of hosted workloads. The network underpins core services such as EC2 compute, S3 storage, and content delivery, making it one of the most trafficked routing domains on the internet. Registered in the United States, AS16509 appears in routing and abuse datasets more often than almost any other network because of the sheer volume of applications hosted on AWS. When an address resolves here, its geolocation points to an AWS availability zone rather than to a specific user of the hosted application.
