    What is a target?
  • One target is one networked application running on one machine and listening on one port.
  • That program running on 10 machines constitutes ten targets.
  • Ten instances of that program (on ten different ports) running on one machine likewise constitute ten targets.
  • If that application uses two ports, both of which need to be checked, it constitutes two targets.
