title: can I bind() to in6addr_any( ie ::) and sendto() localhost
body: <p>I am trying to write a sample client and server</p>
  
  <p>now <code>sever.c</code> would</p>
  
  <ol>
  <li>create a v6 UDP socket </li>
  <li>bind() to in6addr_any ie <code>::</code></li>
  <li>recvfrom() (after sendto succeeds on client side)</li>
  </ol>
  
  <p>in <code>client.c</code> would</p>
  
  <ol>
  <li>create a v6 udp socket</li>
  <li>sendto() <code>::ffff:127.0.0.1</code></li>
  </ol>
  
  <p>My query would be is this scenario correct or am I missing something?</p>
  
  <p>Because the <code>sendto()</code> on the client side is successful but <code>recvfrom()</code> hangs on the server side</p>
  
  <p>Any help??</p>
  
  <p>regards</p>
