    • Even though I try to stay impartial, a couple of things are worthy of
      note here. AS455 (Telianet) may want to check a possible leak as an
      increase of 455 Classful routes seems a little hard to belive. Others
      in the top part of the Added routes delta may want to do the same. This also
      pushed the table over the 43K range ;-(. The intent is not to pick on any
      provider inparticular as clearly you can see a lot of benefit could be gained 
      by a lot of providers aggregating.
      
      The other point is the routing table size trend is not looking good. It's
      rising rapidly. Even in the five weeks I've been doing this again 
      the trend is certainly worrying.

      Even though I received a number of personal notes saying how useful 
      this report is it doesn't seem to have any effect (well not short-term
      anyway). Oh well...

        * 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        *       A summary of the last weeks changes in terms of withdrawn and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.
