+ <font face="Courier New" size="2"> <b>ip dhcp pool</b></font><font face="Arial" size="2"> command
+ defines which addresses will be assigned to hosts.<p>The first command, </font>
+ <font face="Courier New" size="2"> <b>ip dhcp pool</b></font><font face="Arial" size="2">,
+ creates a pool with the specified name and puts the router in a
+ specialized DHCP configuration mode. In this mode, use the </font>
+ <font face="Courier New" size="2"> <b>network</b></font><font face="Arial" size="2"> statement to define the range of addresses to be
+ leased. <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"> If specific addresses on the network are to be excluded,

+ <font face="Courier New" size="2"> <b>ip dhcp excluded-address</b></font><font face="Arial" size="2"> command may be used to

+ <p>Typically, a DHCP server will be configured to assign much more than
+ an IP address. Other IP configuration values such as the default
+ gateway can be set from the DHCP configuration mode. Using the

+ </font>
+ <font face="Courier New" size="2"> <b>default-router</b></font><font face="Arial" size="2"> command sets the default gateway. The address of the

+ <font face="Courier New" size="2"> <b>netbios-name-server</b></font><font face="Arial" size="2">, can also
+ be configured here. The IOS DHCP server can configure clients with
+ virtually any TCP/IP information.</p>

+ configuration mode are shown in Figure

+ <p>The DHCP service is enabled by default on versions of Cisco IOS that

+ <font face="Courier New" size="2"> <b>no service dhcp</b></font><font face="Arial" size="2"> command.
+ Use the </font>
