Release Notes

  • A Route Origin Authorization (ROA) Change Log has been added to ARIN Online. The ROA Change Log displays a list of all new and modified ROAs of an Organization from the past 365 days. This report can be downloaded as a CSV file upon request. Information about this new feature can be found here.
  • Upon IP resource transfer, source ROAs that contain resources involved in the transfer will be recreated to reflect the changes that had been made in the Resource Public Key Infrastructure (RPKI) resource certificate.
