Data Accuracy and Methodology

IPinfo prides itself on delivering highly accurate data. Our ASN information is collected from a variety of reliable sources, including regional internet registries (RIRs) and telemetry from our own proprietary probe network. This data is then cross-verified by our data engineers with other third-party data to guarantee consistency and accuracy. This rigorous approach ensures that the Autonomous System Number database API is both precise and reliable.

Data Retrieval Process

Accessing data through the IP to ASN API is straightforward. The API supports multiple protocols and formats, making it easy to retrieve the data you need in the way that suits you best.

[IPinfo] was the fastest and easiest approach to enable identification of private IPs. Their HTTP API proved to be reliable and performant at the scale we needed which allowed us to avoid building and operating our own service.

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.

Why do some IP addresses not have an associated ASN?

Some IP addresses might not be associated with any ASN, often because they are private or not yet assigned.

What information can be gathered from ASN?

You can gather details like the organization name, country, and associated IP prefixes for both IPv4 and IPv6. IANA has more information about ASNs and their distribution.

Is there a free tier?

Yes, we offer a free account so you can try out the ASN API.
