Introduction
This database provides a reference to determine the autonomous system and number (ASN). An autonomous system (AS) is a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators as a single administrative entity in routing policy.

Database Setup
Below are the steps to set up the database for both IPv4 and IPv6 data.
