What is an ASN?

An Autonomous System Number identifies a network (an ISP, a cloud provider, a large enterprise) that has its own routing policy on the public internet. ASNs are how BGP — the protocol that holds the internet together — knows which network owns which range of IP addresses. AS131591 is the ASN assigned to AMBIT-AS-TW - Ambit Microsystem Corporation.
