3.  From the 'IP Address Distribution' drop-down list, choose either 'DHCP Server', 'DHCP 
Relay' (or 'Disabled' if you want to disable DHCP). 
4.  If you selected 'DHCP Server', the following fields appear: 
Figure  3-189: Defining DHCP Server Parameters 
 
a.  Start IP Address: First IP address that can be assigned to a LAN host. Since the 
device's default IP address is 192.168.1.1, this address must be 192.168.1.2 or 
greater. 
b.  End IP Address: Last IP address in the range that can be used to automatically 
assign IP addresses to LAN hosts. 
c.  Subnet Mask: Mask used to determine to what subnet an IP address belongs 
(e.g.,255.255.0.0). 
d.  WINS Server: The Windows Internet Naming Service (WINS) Server IP address 
that is given in a lease. 
e.  Lease Time In Minutes: Each LAN host is assigned an IP address by the DHCP 
server for a this amount of time, when it connects to the network. When the lease 
expires, the server determines if the computer has disconnected from the 
network. If it has, the server may reassign this IP address to a newly-connected 
computer. This feature ensures that IP addresses that are not in use become 
available for other computers on the network. 
f.  Provide Host Name If Not Specified by Client: If the DHCP client does not 
have a host name, the device automatically assigns one. 
g.  Use Additional DNS Server: The additional DNS server address allows the 
network administrator to provision the DHCP clients with another DNS server 
(other than the device itself).
