extended to support queries with an empty Question Section (a QDCOUNT
of zero (0)), provided that an OPT record is present with a COOKIE
option. Such servers will send a reply that has an empty
Answer Section and has a COOKIE option containing the Client Cookie
and a valid Server Cookie.</pre><pre class="gmail-newpage" style="font-size:13.3333px;margin-top:0px;margin-bottom:0px;break-before:page;color:rgb(0,0,0)"><br></pre><pre class="gmail-newpage" style="font-size:13.3333px;margin-top:0px;margin-bottom:0px;break-before:page;color:rgb(0,0,0)"><br></pre><pre class="gmail-newpage" style="font-size:13.3333px;margin-top:0px;margin-bottom:0px;break-before:page;color:rgb(0,0,0)"><span style="color:rgb(34,34,34);font-family:Arial,Helvetica,sans-serif;font-size:small;white-space:normal">Thank you,</span></pre><pre class="gmail-newpage" style="font-size:13.3333px;margin-top:0px;margin-bottom:0px;break-before:page;color:rgb(0,0,0)"><span style="color:rgb(34,34,34);font-family:Arial,Helvetica,sans-serif;font-size:small;white-space:normal">Egon Kocjan</span>
