      It is not checked before it leaves my workstation.  However, hopefully 
      you will find this report interesting and will take the time to look 
      through this to see if you can improve the amount of aggregation you 
      perform.
      
      The report is split into sections:
      
         0) General Status
         
            List the route table history for the last week, list any possibly
            bogus routes seen and give some status on ASes.
      
         1) Gains by aggregating at the origin AS level
      
            This lists the "Top 30" players who if they decided to aggregate
            their announced classful prefixes at the origin AS level could 
            make a significant difference in the reduction of the current 
            size of the Internet routing table. This calculation does not 
            take into account the inclusion of holes when forming an aggregate
            so it is possible even larger reduction should be possible.
      
         2) Weekly Delta
      
            A summary of the last weeks changes in terms of withdrawn and
            added routes. Please note that this is only a snapshot but does 
            give some indication of ASes participating in CIDR. Clearly,
            it is generally a good thing to see a large amont of withdrawls.
      
         3) Interesting aggregates
      
            Interesting here means not an aggregate made as a set of 
            classful routes.      
      
      Thanks to xara.net for giving me access to their routing tables once a
      day. 
      
      Please send any comments about this report directly to me.
      In the future I hope to put some (or most) of this report up on the
      web.

      2) Weekly Delta
      
      This a daily snapshot of changes in classful routes being withdrawn and added.
      the deltas are calculated over a rolling 7 day period. Please bear in mind this
      is purely a "snapshot" and a large flucuation could be caused by a connectivity
      problem for example. However, this does give some indication of service
      providers that are moving to classless routing.
