title: What does the bind parameter do in Redis?
body: <p>What is the <code>bind</code> parameter in Redis? The documentation for <code>bind</code> assumes that I already know what <code>bind</code> means (which I don't). Does <code>bind</code> set the IP address of:</p>
  
  <ul>
  <li>the <code>Redis</code> server? (I think this is the correct answer, but then I don't understand why we need that)</li>
  <li>the client that will be authorized to connect to Redis? (I tried and it didn't work, so probably incorrect)</li>
  </ul>
