title: Detecting local IP address under FireMonkey3
body: <p>Need to detect local IP address under FireMonkey3. In VCL version, I have been using unit <strong>WinSock</strong> with methods for it</p>
  
  <pre><code>WSAStartup(...)
  gethostname(...)
  </code></pre>
  
  <p><strong>One limitation:</strong> don't need to use any third-party library. I am porting ASTA components to FireMonkey3 platform, and don't want to do dependencies among components.</p>
