title: How do I interpret 'netstat -a' output
body: <p>Some things look strange to me:</p>
  
  <ul>
  <li>What is the distinction between 0.0.0.0, 127.0.0.1, and [::]?</li>
  <li>How should each part of the foreign address be read (part1:part2)?</li>
  <li>What does a state Time_Wait, Close_Wait mean?</li>
  <li>etc.</li>
  </ul>
  
  <p>Could someone give a quick overview of how to interpret these results?</p>
