title: UDP port 0.0.0.0
body: <p>I have a system that is running on windows. 
  I have in that system a process that waits for another process on the same machine for a udp message. The message itself is not important (garbage), but the important thing is that I got the event of the message itself.</p>
  
  <p>The problem is that it seems that I get from another local program a UDP message and I don't know from where. I added information about the sender in the recieved UDP message. I see that I get message from valid local port but also from the addres 0.0.0.0 . </p>
  
  <p>I can't understand the 0.0.0.0 . Does anyone has an idea ?</p>
