ASN
Autonomous System Number: a unique identifier assigned to a network on the internet.
An ASN (Autonomous System Number) is a unique number that identifies a network or group of IP addresses managed by a single organization. Every ISP, hosting provider, and large company that operates its own network has an ASN. For example, Cloudflare is AS13335 and Google is AS15169. ASNs are used by routers to determine how to send traffic across the internet. When you look up an IP address, the ASN tells you which organization owns that part of the internet.
