php checkdnsrr function only works for dotcom domains?
<p>checkdnsrr only works for dot com domains?</p>

<p>If I use live.com (or any existing dotcom), the checkdnsrr returns a value of 1 (TRUE), but it always return a empty string for an existing dot net/org.  It does not matter if the check is for  A or MX or NS... records.  Is the syntax correct or something else?</p>

<pre><code>&lt;?php
$dom ="live.net";
$check = checkdnsrr($dom,'NS');
echo "live $check test ";
?&gt;
</code></pre>

<p>TIA</p>
