title: Send message to all connected machines using Delphi using UDP or other low level technique?
body: <p>I am making a game and want to talk to all the clients at once from my game server. (Original question: How to make a list of IPs, updated question: how to do a UDP broadcast.)</p>
  
  <p>And i want to make a LAN connections between the players.
  Now i dont understand how to find all connected machines to send them a message with server information.
