ASN - Autonomous System Number

An ASN is a unique identifier associated with an AS (Autonomous System) which is used by a variety of routing protocols. The IANA (Internet Assigned Numbers Authority) is responsible for allocating blocks of ASN to RIR (Regional Internet Registry). RIR will then allocate ASN directly to AS operators.
