Release Notes

We completed a number of infrastructure improvements and bug fixes, including:

  • To provide a new way for users to add Internet Routing Registry (IRR) updates, we added a RESTful Application Programming Interface (API). This API allows you to use Representational State Transfer (REST) commands in scripts or software to create, view, and update routing information. Visit for more information.
  • Added guidance in ARIN Online for the organization creation process with regards to Registration Services Agreements (RSAs). These updates reflect process changes that are scheduled for implementation on 1 March 2021.
  • The system will now send courtesy email notifications to prior email addresses when users update to a new email address.
  • Continued to update the underlying architecture and add improvements to the interface of ARIN’s internal management software to allow staff to more easily access data and provide better customer support.
  • Made improvements to monitoring and logging to provide better statistics to staff about ARIN system operations.
