What is an autonomous system number (ASN)?

ASN is the acronym for Autonomous System Number. The Internet is a network of networks. A network made up by the joint operation of thousands of networks that belong to different institutions which, in turn, have different functions: access providers, content providers, universities, Internet users, government agencies, etc. These networks that make up the Internet are known as autonomous systems (AS).
