title: A good unique identifier as default values in MVC models?
body: <p>In order to avoid duplicate entries from same machine that access the WebApp, I am currently looking for the least complex unique identifier as the default values in my MVC models (besides ID).</p>
  
  <p>I am thinking on using MAC (assume it is on same network) as default values. But I don't know how to set it up.</p>
