The DHCP (Dynamic Host Control Protocol) package does not come with a prebuilt file they do provide an example:

ddns-update-style interim;
ignore client-updates;

subnet netmask {

# — default gateway
option routers;
option subnet-mask;

option nis-domain;
option domain-name;
option domain-name-servers;

option time-offset -18000; # Eastern Standard Time
# option ntp-servers;
# option netbios-name-servers;
# — Selects point-to-point node (default is hybrid). Don’t change this unless
# — you understand Netbios very well
# option netbios-node-type 2;

range dynamic-bootp;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
host ns {
hardware ethernet 12:34:56:78:AB:CD;

Do not forget that the DHCP requires a declaration for each network the server is attached to. Or you can just use the /etc/sysconfig/dhcp file to set DHCPDARGS=eth0 or to the interface that is being used.
