  Timing windows exist within which SETIPs are issued in multiple
  locations for the same IP Address. This is usually associated
  with DVIPA takeover/takeback scenarios when the IP address has
  not yet been unregistered at the location giving up the address
  via a DELIP before the SETIP is issued.  It can also occur
  when multiple devices are initializing and one does not know
  the IP Address is also being activated on a partner system.
