Consultation Description

ARIN has been engaged in a multi-year project to create and deploy a new and improved Internet Routing Registry (IRR). On 10 June 2020 (, we launched IRR-online, an authenticated and web-based service designed to make it simple for users to publish routing information via ARIN’s website. At that time, the existing IRR-email system was temporarily left in place to allow organizations to continue using email-based updates to publish routing information (in the ARIN-NONAUTH data stream).

On 1 February 2021 (, we deployed a RESTful API to provide a way to securely automate updates to objects in ARIN’s authenticated IRR service.

With the availability of automation for ARIN’s new IRR system, we intend to retire ARIN’s previous non-authenticated, email-based IRR service at the end of September 2021. We are providing advance notice of this plan so that organizations using the non-authenticated and email-based IRR will have time to switch publication of their routing registry information to a more current solution. Similarly, by establishing a firm end date for the non-authenticated and email-based IRR, organizations making use of the outdated and non-authenticated IRR data stream can be ready for when ARIN ceases publishing the ARIN-NONAUTH data stream.

The authenticated IRR is available to all ARIN resource holders that have resources covered by a signed Registration Services Agreement (RSA) or Legacy Registration Services Agreement (LRSA). Organizations with resources not currently under an RSA/LRSA that wish to use the authenticated IRR may contact ARIN’s Registration Services Department for assistance with bringing those registrations under an RSA/LRSA.

We recognize that this change will have significant impacts on our customers and, as always, we’re interested in your feedback regarding this proposed transition. In particular, we would appreciate hearing from the ARIN community regarding these aspects of the proposed transition:

  1. For those using ARIN’s email-based and non-authenticated IRR system, does the proposed shutdown date of 30 September 2021 provide sufficient time for migration to another IRR system?

  2. For those making use of the ARIN-NONAUTH data stream, is there any reason to provide this information beyond the system shutdown date?

The community feedback provided during this consultation will help inform how we move forward. Please provide comments to You can subscribe to this mailing list at:

ARIN Actions

ARIN thanks everyone who provided valuable feedback during this consultation on the future of ARIN’s unauthenticated IRR. Input provided by the community is a vital part of our planning processes at ARIN, and after reviewing responses to the consultation, we are making a few significant adjustments in our path forward.

One concern raised during the consultation was that six months was not enough time for organizations that currently depend on data in ARIN’s unauthenticated IRR to make changes to their systems. As a result, we will be extending the availability of ARIN’s non-authenticated IRR for an additional six months with final retirement set for 31 March 2022.

The second major suggestion was that ARIN conduct proactive engagement to notifying customers who currently use our unauthenticated IRR. We have already initiated this outreach, and for the next twelve months, we will continue this direct outreach to customers who have records in ARIN’s non-authenticated IRR to inform them of their options and provide necessary assistance.

We will also provide regular reminders and updates to our community and organizations making use of the outdated and non-authenticated IRR data stream so they can be ready for when we cease publishing the ARIN-NONAUTH data stream. These reminders leading up to the retirement of ARIN’s non-authenticated IRR will include statistics on the number of records remaining in that system and related routing coverage.

Thank you again to those who provided valuable feedback on this consultation.
