AS overview

Autonomous Systems (ASes) are network operators or routing domains that form part of the internet's routing infrastructure. Each AS is identified by a unique Autonomous System Number (ASN).

CyberGreen uses AS-level reference data to support more detailed analysis of internet infrastructure conditions than is possible through country-level indicators alone. Want ASN-level analysis? Use the API.

This page lists countries and the ASes associated with them in CyberGreen's reference data.

The table below shows countries and the Autonomous Systems associated with them based on Regional Internet Registry (RIR) allocation data.
