Autonomous System Number (ASN)

An Autonomous System Number (ASN) is a unique identifier assigned to a group of IP networks that operate under the same management and share a common routing policy. Think of it like a phone number for large organizations, allowing them to send and receive internet traffic efficiently. ASNs are crucial for internet routing, enabling different networks to communicate and exchange data. They help ensure that information finds the best path through the complex web of networks that make up the Internet, supporting everything from personal browsing to global commerce.
