AS Summary
         17503  Number of ASes in routing system
          7138  Number of ASes announcing only one prefix
          1399  Largest number of prefixes announced by an AS
                AS7018 : ATTW AT&T WorldNet Services
      62877184  Largest address span announced by an AS (/32s)
                AS721  : DNIC DoD Network Information Center

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').
