Update: This blog has been updated to reflect ARIN’s revised deadline for the IRR transition.

With the April 2022 deadline for ARIN’s IRR transition fast approaching, here’s what network operators need to know now:

Read on for further explanation, including how to prepare for the April 4, 2022, deadline.

Why the Internet Routing Registry?

The American Registry for Internet Numbers (ARIN) New Window IconDecorative icon to indicate a new browser window (opens in a new window) provides a service, known as the Internet Routing Registry (IRR) New Window IconDecorative icon to indicate a new browser window (opens in a new window), that allows network operators to publish their routing policies. Network operators, including research and education campuses, publish their routing policies via an IRR to better protect the routing security of their networks. For example, using ARIN’s IRR service, a campus can publish the set of IP numbers that should be announced for its networks, helping to prevent other organizations from hijacking or otherwise misusing the IP numbers belonging to the campus.

As a part of their more robust assurance practices, networks upstream of a campus – such as state and regional networks, internet service providers, and Internet2 – can use a campus’s IRR entries to ensure they are accepting and forwarding traffic consistently with the campus’s published policy. Networks such as Google, Amazon, and Hurricane Electric also use IRR information to determine whether or not to accept routes.

Many of the networks that interconnect with Internet2, including those mentioned above, will accept Internet2 routes only from organizations that have published their routing policy via the IRR. If an organization’s IRR information is incorrect or missing, Google’s traffic would no longer flow over that organization’s Internet2 connection. Network users would still have access to Google, but that traffic would take the slower – and sometimes more costly – commodity connection.

ARIN to Decommission Legacy IRR in April

ARIN is in the process of transitioning to a new version of the IRR and will decommission the legacy IRR on April 4, 2022. Because the new IRR has different authentication requirements and more advanced services, ARIN will NOT automatically migrate information from the non-authenticated IRR to the new and improved version. 

Network operators must migrate their information to ARIN’s new authenticated IRR, or another IRR (e.g., RADB, RIPE, APNIC, AFRINIC, ARIN, LACNIC, NTT, Level3), by April 4. Otherwise, those network operators will no longer have a published routing policy, and networks such as Google may stop accepting some of Internet2’s routes as a result.

How to Prepare for the ARIN IRR Transition

Here’s what you can do to prepare for the decommissioning of ARIN’s legacy IRR:

These reports are organized by the Internet2 connector. If you see a network for your organization that has Column J colored red, that network’s IRR records will likely disappear after April 4. To prevent this from affecting your Internet2 connection, you’ll need to create a new record in ARIN’s new IRR or another IRR such as Merit’s RADB.
