Setting DHCP server in rhel ,fedora

#Steps to Configure dhcp...
#First give static ip for the server machine ie dhcp server

#1.Packages needed
#-dhcp-

yum -y install dhcp

#2.Copying the config file from
#    /usr/share/doc/dhcp*/dhcpd.conf to /etc/dhcp/dhcpd.conf
echo "Configuration files are"
rpm -qc dhcp

cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf

echo "Configuration Files Copied"

#3.Opening the config file
vim /etc/dhcp/dhcpd.conf

#4.Starting and Chkconfig the service . After adding needed subnetworks

service dhcpd start
chkconfig dhcpd on

echo "Service started and chkconfig is on"

# This is a very basic subnet declaration.

# This declaration allows BOOTP clients to get dynamic addresses,
# which we don't really recommend.

#  range dynamic-bootp 10.254.239.40 10.254.239.60;
#  option broadcast-address 10.254.239.31;
##  option routers rtr-239-32-1.example.org;

# A slightly different configuration for an internal subnet.
#subnet 10.5.5.0 netmask 255.255.255.224 {

#  option broadcast-address 10.5.5.31;
#  default-lease-time 600;
#  max-lease-time 7200;
#}

# Hosts which require special configuration options can be listed in
# host statements.   If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.

#host passacaglia {
#  hardware ethernet 0:0:c0:5d:bd:95;
#  filename "vmunix.passacaglia";
#  server-name "toccata.fugue.com";
#}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
#host fantasia {
#  hardware ethernet 08:00:07:26:c0:a5;
#  fixed-address fantasia.fugue.com;
#}

# You can declare a class of clients and then do address allocation
# based on that.   The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.

##class "foo" {
#  match if substring (option vendor-class-identifier, 0, 4) = "SUNW";
#}
#
#shared-network 224-29 {
#  subnet 10.17.224.0 netmask 255.255.255.0 {
#    option routers rtr-224.example.org;
#  }
#  subnet 10.0.29.0 netmask 255.255.255.0 {
#    option routers rtr-29.example.org;
#  }
#  pool {
#    allow members of "foo";
#    range 10.17.224.10 10.17.224.250;
#  }
#  pool {
#    deny members of "foo";
