IP ASN Data

Available in: IPinfo Lite (Limited), IPinfo Core, IPinfo Plus, and IPinfo Enterprise

Along with detailed ASN information, the paid API tiers provide access to the dedicated ASN API service, which returns information related to the ASN (Autonomous System Number) of the current or queried IP.

In the IPinfo Lite plan, the API will return the ASN, AS Organization name, and AS Domain name.
In the IPinfo Core and IPinfo Plus API tiers, you will have access to the ASN, AS Organization name, AS Domain name, and AS type. IPinfo Plus additionally includes the date the ASN record was last changed. This also includes access to the ASN API service (ASN → ASN Information).
In the IPinfo Enterprise API services, you will have the ASN, AS Organization name, AS Domain name, AS type, and AS route/prefix information for the queried IP address. This also includes access to the ASN API service for ASN Information.

IPinfo Lite

IPinfo Lite returns limited ASN data as part of the broader IP lookup response, including the ASN, AS Organization name, and AS Domain name.
