Hi FYI - this was posted a few minutes ago on arin-announce and may be of interest to NANOG as well.

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. Detailed documentation on these differences 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. A demo of this service has been available since October 2009. The demonstration service is available at: http://whoisrws-demo.arin.net. ARIN continues to welcome community participation on the Whois-RWS mailing list, and we invite you to subscribe and share your thoughts and suggestions at: http://lists.arin.net/mailman/listinfo/arin-whoisrws More detailed information on these changes and other future features that may impact the community at ARIN is available at: https://www.arin.net/features/ Regards, Mark Kosters Chief Technical Officer American Registry for Internet Numbers (ARIN) ----- End forwarded message -----
