ASN (Autonomous System Number) Is a unique identifier assigned to each autonomous system on the internet. Autonomous System (AS) is a collection of routers and networks typically managed by a single organization, having a unified routing policy Merging 5 RIP(afrinic, apnic, arin, lacnic, ripe ncc) provided WHOIS database Functions of ASN Routing Decisions: ASN is used in BGP(Border Gateway Protocol) to exchange routing information, helping the internet route data between different autonomous systems Network Management: ASN allows network operators to control and manage their network's routing policies and behaviors Unique Identification: Each ASN is unique globally, ensuring that data packets can be routed accurately to their destinations Types of ASN Public: Assigned by the Internet Assigned Numbers Authority (IANA) for use in public networks, with a range from 1 to 64511 Private: Used for internal networks, with a range from 64512 to 65535
