Change to Management of the Trust Anchor Locator (TAL) for ARIN’s RPKI Service

Posted: Thursday, 29 September 2022

On 26 September 2022, ARIN announced changes to the way we manage our Trust Anchor Locator (TAL), and specifically changes to our Relying Party Agreement (RPA) that support this change. Community members responded with questions about these changes as they relate to the ARIN TAL. The RPA has been updated once more to clarify that public distribution of the ARIN TAL, including by embedding the ARIN TAL in Relying Party software, is specifically allowed.

The updated RPA is available for review:

We hope this addresses concerns raised by members of the community seeking clarification regarding the use of the ARIN TAL. Thank you to the community for the constructive feedback.
