title: Get MAC using scapy and an IP
body: <p>I'm sending an ARP request using this line and what I basically want is to get the MAC from what's returned:</p>
  
  <pre><code>result = sr(ARP(op=ARP.who_has, psrc='X.X.X.X', pdst='Y.Y.Y.Y'))
  </code></pre>
  
  <p>how would I retrieve the mac from result[0]?</p>
