      To capture, alter, and retransmit a communication stream in a way that
      misleads the recipient. As used by hackers, refers especially to altering
      TCP/IP packet source addresses or other packet-header data in order to
      masquerade as a trusted machine. This term has become very widespread and
      is borderline techspeak. Interestingly, it was already in use in its modern
      sense more than a century ago among Victorian telegraphers; it shows up in

From The Free On-line Dictionary of Computing (30 December 2018) :

     A technique used to reduce network overhead, especially in
     wide area networks (WAN).
     Some network protocols send frequent packets for management
     purposes.  These can be routing updates or keep-alive
     messages.  In a WAN this can introduce significant overhead,
     due to the typically smaller bandwidth of WAN connections.
     Spoofing reduces the required bandwidth by having devices,
     such as bridges or routers, answer for the remote devices.
     This fools (spoofs) the LAN device into thinking the remote
     LAN is still connected, even though it's not.  The spoofing
     saves the WAN bandwidth, because no packet is ever sent out on
     the WAN.
     LAN protocols today do not yet accommodate spoofing easily.
