Hi Alex,

Two quick points:

* The RA route servers no longer exist. Around January 1 of this year, the NSF 
sponsored route servers were decomissioned. At serveral exchange points, Route 
Server services are now being provided by the commercially funded RSNG project 
(see http://www.rsng.net).  Other aspects of the RA project (including some 
research, RPSL, and IRR management/development) have continued.

* The RSNG route servers announce routes according to policy registered in the 
IRR. Any routes not explicitly allowed by policy (RFC-1918 routes, default, 
etc.) are effectively filtered in announcements to all RS peers.
