Release Notes

  • ARIN now allows RESTful calls with the more secure method of sending the API token in a header as a preferred alternative to sending the API token in the URL. Additional information can be found in ARIN’s Reg-RWS Quick Start Guide, the Restful Methods page, and the RPKI and IRR API documentation. This closes Suggestion 2022.5.
  • The restriction at account creation preventing non-human service accounts has been removed, and ARIN now accepts such accounts. This closes Suggestion 2022.11.
  • Minor improvements and bug fixes were made to improve the customer experience.
