DUPLICATE AND DAMAGED PACKETS
     Ping will report duplicate and damaged packets.  Duplicate packets should
     never occur when pinging a unicast address, and seem to be caused by in-
     appropriate link-level retransmissions.  Duplicates may occur in many
     situations and are rarely (if ever) a good sign, although the presence of
     low levels of duplicates may not always be cause for alarm. Duplicates
     are expected when pinging a broadcast or multicast address, since they
     are not really duplicates but replies from different hosts to the same
     request.

     Damaged packets are obviously serious cause for alarm and often indicate
     broken hardware somewhere in the ping packet's path (in the network or in
     the hosts).
