title: Explain the instance properties of System.Net.IPAddress
body: <p>I'm having a little trouble understanding the <a href="http://msdn.microsoft.com/en-us/library/system.net.ipaddress.aspx" rel="noreferrer"><code>System.Net.IPAddress</code> class</a>, because I don't know where to look for a definition of what some of the properties are referring to.  Specifically, what are:</p>
  
  <pre><code> IPAddress.IsIPv6LinkLocal
   IPAddress.IsIPv6Multicast
   IPAddress.IsIPv6SiteLocal
   IPAddress.IsIPv6Teredo
  </code></pre>
  
  <p>I will also happily accept an answer that points to a resource that explains these concepts.  The MSDN site has proved insufficient.</p>
