We have corrected the issues that impacted the first release and are now able to bring you the following services that provide the general public with access to ARIN's registration data: * a RESTful Web Service (RWS) * a NICNAME/WHOIS port 43 service * a user-friendly web site (http://whois.arin.net) When using the Whois-RWS you will notice some differences in behavior for certain queries and corresponding result sets on the NICNAME/WHOIS port 43 service. The detailed documentation on these differences has been updated and is now available at: https://www.arin.net/resources/whoisrws/whois_diff.html ARIN?s Directory Service for registration data has used the NICNAME/WHOIS protocol since its inception. The limitations of the NICNAME/WHOIS protocol are well known and documented in RFC3912. Whois-RWS was created as an alternative to the ARIN Whois and will provide much richer functionality and capability to the community. ARIN continues to welcome community participation on the Whois-RWS mailing list, and we invite you to subscribe and share your experience and feedback about the new service: http://lists.arin.net/mailman/listinfo/arin-whoisrws Regards, Mark Kosters Chief Technical Officer American Registry for Internet Numbers (ARIN) ----- End forwarded message -----
