New Features Added to ARIN’s Registration Data Access Protocol Service
Posted: Wednesday, 21 May 2025
Service Update
ARIN’s Registration Data Access Protocol (RDAP) service has been enhanced with an enriched search functionality, allowing users to make new queries that are equivalent to those available through the Whois-RWS service. Information on these new calls can be found at Whois/Registration Data Access Protocol (RDAP).
Our work on this release has been completed, and all ARIN systems are operating normally. We thank you for your patience. If you have additional questions, comments, or issues, please submit an Ask ARIN ticket using your ARIN Online account or contact the Registration Services Help Desk by phone Monday through Friday, 7:00 AM to 7:00 PM ET at +1.703.227.0660.
Regards,
Mark Kosters
Chief Technology Officer
American Registry for Internet Numbers (ARIN)
