Just a point on the curve but... ARIN has made a deliberate decision to move emphasis over to their RESTful Web Interface, Whois-RWS. Part of the reason is performance and part of the reason is for granularity of the data available. They really REALLY want people to make that move although they will continue to support the old whois for a lot of the basic stuff. https://www.arin.net/resources/whoisrws/index.html I believe one of the things I heard at last years NANOG / ARIN conference here in Atlanta was that they would no longer be providing certain information such as reverse DNS servers in the old whois because that's now in a different database or some such. On another closed security forum on which I participate someone was having problems getting at Abuse POC information. There a parameter for that as well but they prefer using the Whois-RWS interface and API instead. I think we'll be hearing more of that as time goes on.
