− | '''ASN''' is an acronym for '''Autonomous System Number'''. ASNs are globally unique numbers and significant part of the Internet routing architecture known as the [[Autonomous System]]. Autonomous System Numbers are taken from a 16-bit number field. There are reserved ASNs, including 0 and 65,535, which can be used to identify non-routed networks. ASNs starting from 64,512 up to 65,534 are reserved for private use while the ASN 23,456 is dedicated to be used in the ASN pool transition.<ref>
