AS Summary
         16121  Number of ASes in routing system
          6426  Number of ASes announcing only one prefix
          1410  Largest number of prefixes announced by an AS
                AS701  : ALTERNET-AS UUNET Technologies, Inc.
      73534720  Largest address span announced by an AS (/32s)
                AS568  : SUMNET-AS DISO-UNRRA


Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as 
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').
