ASN Meaning and
Definition
-
ASN stands for Autonomous System Number. It is a unique identifier assigned to an Autonomous System (AS) in a computer network. An Autonomous System can be defined as a group of IP networks that operate under a common administration and follow a consistent routing policy on the internet.
An ASN serves as a means of distinguishing and categorizing individual networks within the larger framework of the internet. It helps in facilitating efficient routing of network traffic by enabling routers to exchange network reachability information. Each Autonomous System is identified by its unique ASN, which is a 16-bit number ranging from 1 to 65,535.
ASN numbers are assigned by Regional Internet Registries (RIRs) or Local Internet Registries (LIRs) to organizations that operate their own network infrastructure. The assignment process involves a request made by the organization, followed by an assessment of eligibility and justification of the need for an ASN. Once assigned, the ASN is registered in a global database known as the Autonomous System Number Registry, which helps in tracking and managing network resources.
The ASN plays a crucial role in the routing system of the internet, as it allows routers to establish connections, exchange routing information, and select the most efficient paths for traffic flow. Additionally, ASN numbers are utilized in analyzing network performance, diagnosing network issues, and monitoring internet traffic.
