InetAutonomousSystemNumber
Represents an autonomous system number that identifies an Autonomous System (AS). An AS is a set of routers under a single technical administration, using an interior gateway protocol and common metrics to route packets within the AS, and using an exterior gateway protocol to route packets to other ASes'. IANA maintains the AS number space and has delegated large parts to the regional registries. Autonomous system numbers are currently limited to 16 bits (0..65535). There is, however, work in progress to enlarge the autonomous system number space to 32 bits. Therefore, this textual convention uses an Unsigned32 value without a range restriction in order to support a larger autonomous system number space.
