Sure,
In my case I segregate the IPs that are allowed for known and unknown
clients. I suspect that there are other ways of doing this, but I like
this way!
ie:
# /etc/dhcp3/dhcpd.conf
# I am the grand poo-bar (fear me)
authoritative;
# Where to put the noise
log-facility syslog;
# update the DNS?
ddns-update-style none;
# do nothing on this subnet
subnet X.X.X.0 netmask 255.255.255.0 { }
# local subnet
subnet 10.10.100.0 netmask 255.255.255.0 {
default-lease-time 1200;
max-lease-time 7200;
option dhcp-max-message-size 2048;
allow unknown-clients;
range 10.10.100.200 10.10.100.230;
# PXE FAI booters
group {
deny unknown-clients;
boot-unknown-clients false;
allow booting;
use-host-decl-names on;
default-lease-time 86400;
max-lease-time 604800;
server-name fatcon;
next-server fatcon;
filename "fai/pxelinux.0";
# worker bees
host bill { hardware ethernet XXXX; fixed-address 10.10.100.30; }
host ben { hardware ethernet XXXX; fixed-address 10.10.100.31; }
host donald { hardware ethernet XXXX; fixed-address 10.10.100.32; }
host douglas { hardware ethernet XXXX; fixed-address 10.10.100.33; }
}
}
