What Is an Autonomous System?

An autonomous system (AS) is a collection of IP networks operated by a single organization - an ISP, cloud provider, enterprise, or university - that shares a common routing policy. Each AS is identified by a unique AS number (ASN) and exchanges routing information with other systems using the BGP protocol.

Knowing which ASN an IP belongs to reveals who actually operates the network behind it - useful for fraud analysis, traffic quality assessment, and abuse investigation. Use the IP lookup tool to find the ASN for any address.
