title: Differentiating Between Two Computers On The Same Intranet
body: <p>I am trying to create a Socket "Hello World" program.</p>
  
  <p>I would ideally like to create two programs who can exchange simple text, peer-to-peer.</p>
  
  <p>I can create a webservice that the peers can post their IP Address to.</p>
  
  <p>One peer can then select another to pair up with.</p>
  
  <p>If one of the peers is my desktop computer, and the other is my laptop, how can I differentiate the two?</p>
