probably the bind backend.</div>

<p>(assuming you meant "CNAME" not "CNANE")<br>
</p>
<p>The implication is that there is some other record for "<a
class="moz-txt-link-abbreviated" href="http://www.example.com"
moz-do-not-send="true">www.example.com</a>"<br>
</p>
<p>What does the following command show at that point?</p>
<p>dig @x.x.x.x <a class="moz-txt-link-abbreviated"
href="http://www.example.com" moz-do-not-send="true">www.example.com</a>.
any</p>

<p>Is it possible that you deleted other records for "<a
class="moz-txt-link-abbreviated" href="http://www.example.com"
moz-do-not-send="true">www.example.com</a>" at the same time?<br>
</p>
<p>Again, what does "dig @x.x.x.x <a
class="moz-txt-link-abbreviated" href="http://www.example.com"
moz-do-not-send="true">www.example.com</a>. any" show at this
point, and is it different to case 5?</p>
