Option domain-name "bene.com"; // specify the default search domain

Option domain-name-servers 192.168.1.1, 202.96.128.68; // DNS address

Default-lease-time 21600; // default lease for 6 hours

[Root @ localhost ~] # Service dhcpd start
[Root @ localhost ~] # Chkconfig dhcpd on // Add the running level

[Root @ localhost ~] # Netstat-naup | grep ": 67" // view the dhcpd service port

IV,ConfigurationDHCPClient

[Root @ localhost ~] # Vim/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE = eth0

ONBOOT = yes // start on startup

BOOTPROTO = dhcp

[Root @ localhost ~] # Dhclient-d eth0 // automatically obtain the new IP Address

[Root @ localhost ~] # Dhclient-r eth0 // release and obtain the IP address again

[Root @ localhost ~] # Less/var/lib/dhcpd. leases // view allocated IP addresses
