body: <p>Here is the ANSWER SECTION when I run <code>dig www.google.com</code>:</p>
  
  <pre><code>;; ANSWER SECTION:
  www.google.com.         108     IN      A       74.125.239.115
  www.google.com.         108     IN      A       74.125.239.114
  www.google.com.         108     IN      A       74.125.239.116
  www.google.com.         108     IN      A       74.125.239.113
  www.google.com.         108     IN      A       74.125.239.112
  </code></pre>
  
  <p>I think the first field contains the URL and the second field contains the port number. I am not sure about the third and fourth fields. I think the fifth field contains the IP address.</p>
  
  <p>I've reviewed <a href="http://www.madboa.com/geek/dig/">http://www.madboa.com/geek/dig/</a> and <a href="https://kb.mediatemple.net/questions/909/Understanding+the+dig+command">https://kb.mediatemple.net/questions/909/Understanding+the+dig+command</a>, and am still unsure what each section represents.</p>
