Vad är en ASN?
Ett autonomt system (AS) är en samling anslutna nätverk som fungerar under en gemensam administrativ domän och delar routningspolicyer. Varje AS identifieras av ett unikt Autonomous System Number (ASN), som används för att utbyta routningsinformation med andra ASer. AS kan styra hur trafiken flyter genom nätverk och sedan filtrera bort oönskad trafik.
