AS Summary
         20079 Number of ASes in routing system
          8291 Number of ASes announcing only one prefix
          1485 Largest number of prefixes announced by an AS
                AS7018 : ATT-INTERNET4 - AT&T WorldNet Services
      90504960 Largest address span announced by an AS (/32s)
                AS721 : DLA-ASNBLOCK-AS - 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').
