title: What is it DNSQR?
body: <p>I looked for a script that send a DNS request. I found out a script using "DNSQR", but I'm not sure what is this command, and I didn't find a good documentation for it.<br>
  this is the entire command: <code>qd=DNSQR(qname="www.facebook.com")</code>. </p>
  
  <p>this is the whole script:</p>
  
  <pre><code> my_packet = sr1(IP(dst="8.8.8.8")/UDP(dport = 53)/DNS(rd=1,qd=DNSQR(qname=URL)))
  </code></pre>
