ASN list

An Autonomous System Number (ASN) is a unique number that allows autonomous systems to exchange routing information with other connected systems.

AS numbers are assigned by the Internet Assigned Numbers Authority (IANA) to Internet Regional Registries (RIRs). The RIR then assigns the ASN to objects in its scope. More information can be obtained from the ASN.

On this page you will find a complete and up-to-date list of all ASNs with detailed data for each autonomous system.
