AS Summary
         16536 Number of ASes in routing system
          6635 Number of ASes announcing only one prefix
          1371 Largest number of prefixes announced by an AS
                AS7018 : ATT-INTERNET4 AT&T WorldNet Services
      73517312 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').
