On a DHCP-enabled network, the IP information is assigned dynamically rather than statically. A DHCP client
can be assigned a different address from the pool each time it reconnects to the network.
5.2.2 Why use DHCP?
DHCP allows you to manage and distribute IP addresses throughout your network from the Internet Security
Router. Without DHCP,
you would have to configure each computer separately with IP address and related
information. DHCP is commonly used with large networks and those that are frequently expanded or otherwise
updated.
5.2.3 Configuring DHCP Server
Note
By default, the Internet Security Router is configured as a DHCP

255.255.255.0). To change this range of addresses, follow the
procedures described in this section.
First, you must configure your PCs to accept DHCP information assigned by a DHCP server:
1. Log into Configuration Manager as administrator, click the LAN menu, and then click the DHCP
