AS Summary
         21232  Number of ASes in routing system
          8807  Number of ASes announcing only one prefix
          2158  Largest number of prefixes announced by an AS
                AS8151 : Uninet S.A. de C.V.
      91312384  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').
