About ASNs

An Autonomous System (AS) is a collection of connected IP routing prefixes under the control of one or more network operators that presents common, clearly defined routing policy to the Internet. A unique AS number is allocated to each AS for routing purposes. They are important because the AS number uniquely identifies each network to the Internet.
