                1379  Largest number of prefixes announced by an AS
                      AS701  : ALTERNET-AS UUNET Technologies, Inc.
            73394432  Largest address span announced by an AS (/32s)

      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').
