Log:
  ping: do reverse DNS lookup of the target address
  
  When printing replies, ping will now attempt a reverse DNS lookup of the
  target.  That can be suppressed by using the "-n" option.  Curiously, ping
  has always done reverse lookups in certain error paths, but never in the
  success path.
