NANOGers - If you are using the Origin AS field, please update your systems immediately.
Thanks! /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <[email protected]> Subject: [arin-announce] Autonomous System Originations (Origin AS) Will Be Retired on 28 July Date: June 30, 2025 at 11:26:27 AM EDT To: "[email protected]" <[email protected]> This is the final reminder that the Origin Autonomous System (Origin AS) field will be officially removed from the ARIN database on 28 July. This change follows the ARIN Board of Trustees’ July 2023 adoption of policy ARIN-2021-8, which called for the deprecation of the ‘Autonomous System Originations’ field. We recommend any customers who query the Origin AS database for routing security or operational purposes to transition to a more modern and secure alternative such as Resource Public Key Infrastructure (RPKI) or the Internet Routing Registry (IRR). These tools provide more reliable and secure options for managing and verifying routing information. For help with this transition, please contact our Registration Services Help Desk for guidance by using the “Ask ARIN” feature in your ARIN Online account, or call +1 703.227.0660, Monday-Friday, 7:00 AM-7:00 PM ET. Regards, American Registry for Internet Numbers (ARIN) _______________________________________________ ARIN-Announce _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/75E7X7XDCTJCPWSGNYUZICZCZPA33WI7/
