Here is the top portion of my dhcpd.conf:

###

default-lease-time 8640000;       # one day
max-lease-time 8640000;           # one day
 

ddns-update-style none ;
 

server-identifier dmc.uucp;
option domain-name "uucp";
option domain-name-servers 192.168.24.10;
#option domain-name-servers 24.3.196.33, 24.3.196.34;
option routers 192.168.24.254;
 

# You can have no range but still need subnet information
# on the IF you have dhcpd running on
 

subnet 192.168.24.0 netmask 255.255.255.0 {
         range  192.168.24.31 192.168.24.224;
#
         option subnet-mask 255.255.255.0;
         option broadcast-address 192.168.24.255;
         option routers 192.168.24.254;
 

         option time-offset              -18000;     # Eastern Standard Time
 

# This didn't work at all
         ## If you have Samba acting as a WINS server
         ##
#        option netbios-name-servers 192.168.24.10;
#        option netbios-dd-server 192.168.24.10;
#        option netbios-node-type 8;
#        option netbios-scope "ISO";
}
 

host d {
         hardware ethernet 00:20:AF:F2:EB:FE;
         fixed-address 192.168.24.21;
         option domain-name "uucp" ;
         option smtp-server 192.168.24.10 ;
}

On my network I have my own dns (tinydns/dnscache). The above works
for use with various Windows boxen (needed for school). Note the
commented out 24.x.x.x network. That was the DNS for the old @home
service.
