It seems that you think the host statement can have a limited scope,
limited to a subnet. That is not correct, host statements are global
wherever they are placed. The bad thing about putting them into
subnets is that they will inherit options from the subnet even if
they get addresses from another subnet.<br>
<br>
The server will hand out an address corresponding to the subnet it
sees the discover coming from, it will use the fixed address only if
it matches the subnet the discover comes from, else it will use an
address from the subnet's pool.<br>

<pre wrap="">Hi,
Maybe someone can help me..
I have an intel card with 4 ports.. with incremental mac addresses.
I'm trying to to use the dhcp server 4.2.3.P2 to assign two subnets
based on mac addresses, The server is assigning the first address it
finds close to the mac address. Not sure if my config file is bad..
90:e2:ba:0c:0d:50 should be 10.96.165.16
90:e2:ba:0c:0d:51 should be 172.31.1.16
90:e2:ba:0c:0d:50 sees and offer of 172.31.1.16
