<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">I am not Glen, but I believe it will be random. I have something similar where members of a class may draw from either of two pools. This is intentional where one pool is exclusive
for the class and intended to insure that class is never without an address even if the much larger general pool becomes exhausted.<br>
If you want to isolate the these examples you will need to add the machines to a more specific membership as they match the initial class rule.<br>

<p class="MsoPlainText">You must configure all the subnets where clients are connected in dhcpd.conf, otherwise how can the server know what to send for netmask, default router, etc.</p>
<p class="MsoPlainText"> </p>
<p class="MsoPlainText">dhcpd will only assign the IP address in the pool if it matches the subnet where the request came from. You may need a shared-network in there too if there is one physical network with several subnet ranges configured (10.30.30.0 and
10.70.70.0 perhaps).</p>
