<title>Round robin DNS query response</title>
<font face="Calibri, Verdana, Helvetica, Arial"><span
style="font-size: 11pt;">Hi everyone...<br>
<br>
I am rather new to the world of DNS so I’m hoping to get some of your
expertise...<br>
<br>
Is there a way to make BIND respond DNS query in sequence? For
example, if I assign 2 IP addresses to an A record, is it possible to
have it respond like...<br>
<br>
Client 1 for <a class="moz-txt-link-abbreviated" href="http://www.example.com">www.example.com</a> -> 192.168.1.1<br>
Client 2 for <a class="moz-txt-link-abbreviated" href="http://www.example.com">www.example.com</a> -> 192.168.1.2<br>
Client 3 for <a class="moz-txt-link-abbreviated" href="http://www.example.com">www.example.com</a> -> 192.168.1.3<br>
...and so on.<br>
<br>
I know companies use load balancer for this function, but my customer
in this case don’t really want to make additional investment :P</span></font><br>

Option A: round-robin+sortlist<br>
Option B: views<br>
<br>
Appropriate caveats for each approach.<br>
<br>
Note that if these are Windows clients on the same subnets as the
<a class="moz-txt-link-abbreviated" href="http://www.example.com">www.example.com</a> addresses, you could probably just get away with a
plain old round-robin and rely on the built-in Windows "subnet
prioritization", see
