server. This also means that the range should *not* include this address.
So assume that there is a router, or the dhcp server has a secondary IP
address for each subnet, then you need
option routers 172.31.201.1;
range 172.31.201.2 172.31.201.254;
and so on in each subnet.
Classes operate at the pool level, so you need a pool for each range,
like this:
shared subnet ...
subnet ...
pool {
range ...
allow members of "class_a"
}
}
subnet ...

Thanks for replying.
I can not seem to get the pools to work. The only time I was able to get
a non-error config file where the hosts all were pulling their proper
range, they couldn't ping each other because dhcpd insists that the
netmask be 255.255.255.0 otherwise it throws an error on startup. If I
manually change the netmask on the systems to 255.255.0.0 it works but
that isn't a solution.
So I gave up on that. I have been digging through man pages and
documentation and I can't seem to find an example of what I am trying to
do. I am two days down on this and tired of finding lots of partial
examples that don't work. :-)
Instead, I scrapped it all for the configuration posted below. This
works well enough and knowing that the host declaration is global helps.
Putting the PXE boot information into the group suites my needs for the
moment. However, I now have the problem that for some reason it is _not_
talking to the bind DNS system (on the same host). Nodes that PXE boot
get the right IP yet they can not seem to find their name; they also
can't ping anyone by DNS except for 172.31.200.2. This is very
frustrating. Can anyone spot why dhcpd isn't talking to bind?
Thanks again for the replys!

I wonder why you have a shared-network as there is only one subnet
here?<br>
<br>
I also want to mention that by placing the host statements inside
your shared-network, you will risk some very hard to locate issues
with the hosts inheriting from the apparently wrong places. The
intention is to place the host declarations in the global scope,
i.e. among the options.<br>
