Amazon/AWS ASN
Seeing an IP fall inside AS16509 is one of the fastest ways to confirm a server is hosted on AWS (Amazon Web Services), useful both for infrastructure diagnostics and for investigating the real origin of an IP hidden behind a third-party CDN. The lookup below pulls the holder, announced prefixes and BGP neighbours straight from RIPEstat's public API.
Can vary by region and service.
Useful for infrastructure and abuse investigations.
Holder and prefix count as returned by the RIPEstat API at the time of this lookup.
ASN stands for Autonomous System Number, a number that identifies a network that routes traffic independently on the internet, defining its own routing policy via BGP. Internet service providers, cloud providers, large companies and universities typically have their own.
Not necessarily. Amazon operates multiple ASNs, depending on the service (EC2, CloudFront/CDN, Route 53) and region, the IP may show up under a different ASN, even though it belongs to the same provider.
No. AWS hosts a huge, entirely legitimate slice of the internet. The ASN only tells you who operates the network infrastructure, it says nothing about the content or intent of whoever rents that server.
ARIN (American Registry for Internet Numbers), the regional registry responsible for North America, is the one that assigned this number block to Amazon.com, even though AWS infrastructure runs in regions spread across the entire world.
Because every EC2, Lightsail or other-service customer with a dedicated IP block can generate a distinct prefix in the routing table, multiplied across dozens of regions and millions of active customers, the total passes 22,000, well above what AS15169 or AS13335 show in this same kind of lookup.
Look up an ASN directly (AS15169 or 15169) or an IP address, and the tool finds the ASN announcing that address on the internet. Data comes from RIPEstat, RIPE NCC's public routing statistics API, straight from your browser.
The lookup runs directly from your browser against RIPEstat's public API (RIPE NCC), the J-Kit server never intermediates that call. ASN, prefix and BGP adjacency data are public internet routing data, the same information any network announces to its neighbours.
