Perhaps Wouter can explain that part, as I am sure some conscious design<br>

I'm guessing this is the same anti-feature-creep sentiment as why<br>
round-robinning RRs was left out of NSD. This is unfortunate, because very<br>
few clients bother to use anything but the first IP returned by their<br>
resolver.<div class="im"><br>

This would not be true if <a href="http://cnn.com" target="_blank">cnn.com</a> were served by NSD. The ordering would by<br>
the same, every time, resulting in at least 3x the load reaching the first<br>
IP in the zone file.</blockquote><div><br>Hi Aaron and Paul, <br><br>Thanks for the replies. <br><br>If I read this correctly, this seems to negate the whole point of using dns round robin. <br><br>Depending on what my TTL is set to, all queries will be delivered to the first host, whether<br>
