ASNs
An Autonomous System Number (ASN) is a numeric identifier used in the Border Gateway Protocol (BGP) to identify which autonomous system a particular prefix is originating from or transiting through. NetBox supports both 16- and 32-bit ASNs.
ASNs must be globally unique within NetBox, and may be allocated from within a defined range. Each ASN may be assigned to multiple sites.
Fields
