What is an Autonomous System (AS)?
Autonomous System (AS) numbers group IP address networks and routing prefixes with the same external routing protocols. For example, all IP addresses managed by an organization are typically listed in the same AS network group. This could include all IP address prefixes managed by a university, corporate entity, internet service provider, or similar organization. Autonomous systems are useful for organizing the internet's IP addresses by the administrative entities which manage each IP address subnet. If an organization has multiple routing policies then a unique AS number will be assigned to each group of IP addresses.
