title: Can you talk via IP/TCP without internet?
body: <p>I want to know if you can use a socket() to communicate directly between two computers, with an Ethernet cable directly connecting 1 computer's port to the other.</p>
  
  <p>The issue being, since neither computer is connecting to a router, there's nothing to give either computer an IP address.</p>
  
  <p>Is it possible to make a socket without an IP address?</p>
