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.

Well we do this (we also filter out some other things we
don't want to hear from other people), but this set me
thinking. Is there anyone who actually has a good reason
to propogate default and reserved addresses through the RA?
Wouldn't it be a good move for the RA itself to filter
these announcements (in addition to what's in the policy)?
