ARIN provides access to a bulk copy of all objects in the public ARIN Whois directory service to organizations that will use the data for Internet operational or technical research purposes. ARIN does not provide bulk copies of Whois data to operators who wish to incorporate this data into products, services, or internal systems with no clear benefit to the broader community.
Bulk Whois data contains the Point of Contact (POC) records, organization records, and AS, IPv4, and IPv6 registrations that are displayed in ARIN’s public Whois. You can download a .zip file of the entire bulk Whois data, or selectively download only parts of the Bulk Whois data in either .zip, .txt, or .xml format.
