Hvad er en ASN?
Et autonomt system (AS) er en samling af forbundne netværk, der opererer under en fælles administrativ domæne og deler rute politikker. Hvert AS identificeres af et unikt autonomt systemnummer (ASN), som bruges til at udveksle ruteoplysninger med andre AS'er. AS kan styre, hvordan trafik flyder gennem netværk og filtrere uønsket trafik.
