ASN Database Download

Autonomous System Numbers (ASNs) are crucial for the proper functioning of the internet. They represent collections of IP networks operated by one or more network operators, which manage routing policies. ASNs are important for analyzing and managing networks. They help organizations identify where IP addresses come from, control network traffic, and improve security. 

IPinfo's autonomous system database download provides comprehensive data to gain greater context about the networks.

We needed to further contextualize Internet scanners, crawlers, and bots. Origin networks, data centers, ASNs, and countries are a huge component of that. We were looking for a faster, more developer-friendly alternative to existing geo-IP providers. A close friend of mine hit the IPinfo API with cURL, and I saw all the information we needed.

Frequently Asked Questions

What is ASN?

ASN stands for Autonomous System Number. These numbers identify autonomous systems (AS) that represent a collection of Internet Protocol prefixes. Universities, governments, large organizations, Internet Service Providers (ISP), and others often operate their own IP network which is identified by an ASN.

How are ASNs distributed?

ASNs are determined and assigned by Regional Internet Registries (RIRs). There are five RIRs responsible for allocating and managing IP address spaces and ASNs within their respective geographic regions:
  • • AFRINIC (African Network Information Center) for Africa
  • • APNIC (Asia-Pacific Network Information Centre) for Asia and the Pacific region
  • • ARIN (American Registry for Internet Numbers) for North America
  • • LACNIC (Regional Internet Registry for Latin America and Caribbean) for Latin America and the Caribbean
  • • RIPE NCC (Réseaux IP Européens Network Coordination Centre) for Europe, the Middle East, and parts of Central Asia

How often is the IPinfo ASN database updated?

The ASN database is updated daily to ensure you have the most current data.
