Is it the case that your new hosts are first connected to the<br>
network, each obtaining an address from the ...100 - ...200 range,<br>
and subsequently assigned a fixed address? If so, the DHCP protocol<br>
requires the previously-used address to be used again, if this is<br>
not now forbidden.<br>
<br>
In my experience, simply specifying<br>
<br>
host { ... fixed-address ...; }<br>
<br>
isn't enough to forbid such re-use of an address. You'll need to<br>
use a pool specification.<br>
<br>
Instead of<br>
<br>
range X.X.X.100 X.X.X.200;<br>
<br>
use<br>
<br>
pool {<br>
deny known clients;<br>
range X.X.X.100 X.X.X.200;<br>
}<br>
<br>
I hope this helps.<br>
<br>
<br>
