Abuse of PHP function checkdnsrr
<p>I have a php page which uses the PHP function <code>checkdnsrr</code> repeatedly.</p>

<p>Are their any limits on how many times I can use it in a day/hour/month etc before being banned?</p>

<p>Could my server IP be banned for using it too much?
Are their any other things that could happen if I use it too much?</p>
