What is an Autonomous System (AS)?
An Autonomous System (AS) is a collection of connected networks that operate under a common administrative domain and share routing policies. Each AS is identified by a unique Autonomous System Number (ASN), which is used to exchange routing information with other ASs. AS can control how traffic flows through networks and then filter out unwanted traffic.
