There is also the question of what the addresses in the host
statements are.<br>
<br>
The addresses (looked up from DNS) determine which subnet the hosts
appear in, the placement of the host statements do NOT have any
influence on that (as also Glenn states).<br>

<pre wrap="">Hi Chris
Defining a host record inside a subnet does not cause that host to be
bound or in any way assigned to that subnet. A host definition is, by
definition a global statement.
You need a way to differentiate the two different types of client so they
are restricted to their specific subnet. A client defined in a host
statement is a "known-client", so in your case there are two things to do
to fix the situation:
1) move the host statements outside the subnet and shared-network
definitions.
2) in the first subnet add a pool and deny statement, move the range into
the pool:
pool {
range 10.0.1.65 10.0.1.126;
allow unknown-clients;
}
option routers 10.0.1.3;
option ntp-servers 10.0.1.3;
option broadcast-address 10.0.1.127;
option domain-name "local.lan";
option domain-name-servers 10.0.1.3;
default-lease-time 10800;
max-lease-time 21600;
similarly, in the second subnet add a pool and allow statement, move
the range into the pool:
pool {
range 10.0.1.128 10.0.1.142;
deny unknown-clients;
}
# rest of the original subnet statements ...
There is an example in the ADDRESS POOLS section of the dhcpd.conf man page.

<pre wrap="">Hi all.
I'm trying to configure the dhcp server to grant leases in same subnet but
different cidr classes however it doesn't appear to be working:
* dhcp/dns server and router is 10.0.1.3/255.255.255.0
* any dhcp request should get a short term lease in 10.0.1.64/26
* dhcp requests from specified mac addresses get long term lease in
10.0.1.128/28
shared-network local {
# short term
subnet 10.0.1.64 netmask 255.255.255.192 {
range 10.0.1.65 10.0.1.126;
option routers 10.0.1.3;
option ntp-servers 10.0.1.3;
option broadcast-address 10.0.1.127;
option domain-name "local.lan";
option domain-name-servers 10.0.1.3;
default-lease-time 10800;
max-lease-time 21600;
}
# long term
subnet 10.0.1.128 netmask 255.255.255.240 {
range 10.0.1.128 10.0.1.142;
option routers 10.0.1.3;
option ntp-servers 10.0.1.3;
option broadcast-address 10.0.1.143;
option domain-name "local.lan";
option domain-name-servers 10.0.1.3;
default-lease-time 604800;
max-lease-time 864000;
host solaredge1 {
hardware ethernet 00:27:02:10:65:49;
fixed-address pv-inverter1.local.lan;
}
host solaredge2 {
hardware ethernet 00:27:02:10:30:21;
fixed-address pv-inverter2.local.lan;
}
host cctv-dvr {
hardware ethernet 00:19:<a class="moz-txt-link-freetext" href="fb:e2:ab:1b">fb:e2:ab:1b</a>;
fixed-address cctv.local.lan;
}
}
}
Hostnames in the "long term" range have corresponding A and PTR records in
the
dns zone but they still get "short term" IPs assigned.
What's the right way to implement the setup?
Thanks
-Chris
