# Autonomous System Numbers (ASNs)

ASNs view provides a pie chart representation of the traffic grouped by Autonomous System (AS). An AS is either a single network or a group of networks, controlled by a network administrator on behalf of a single administrative entity (such as a university, a business enterprise, or a business division). An AS is also sometimes referred to as a routing domain. A globally unique number called an Autonomous System Number (ASN) is assigned to each AS.
