|
||
|
|
<div><p>These topics discuss methods for securing the DHCP
|
||
|
|
server for authorized users and preventing access to the DHCP server.</p>
|
||
|
|
<p>Dynamic host configuration protocol (DHCP) provides a framework for passing
|
||
|
|
configuration information to hosts on a TCP/IP network. For your client workstations,
|
||
|
|
DHCP can provide a function similar to auto configuration. A DHCP-enabled
|
||
|
|
program on the client workstation broadcasts a request for configuration information.
|
||
|
|
If the DHCP server is running on your system, the server responds to the request
|
||
|
|
by sending the information that the client workstation needs to correctly
|
||
|
|
configure TCP/IP. </p>
|
||
|
|
<p>You can use DHCP to make it simpler for users to connect to your system
|
||
|
|
for the first time. This is because the user does not need to enter TCP/IP
|
||
|
|
configuration information. You can also use DHCP to reduce the number of internal
|
||
|
|
TCP/IP addresses that you need in a subnetwork. The DHCP server can temporarily
|
||
|
|
allocate IP addresses to active users (from its pool of IP addresses).</p>
|
||
|
|
<p>For thin clients, you can use DHCP in place of BOOTP. DHCP provides more
|
||
|
|
function than BOOTP, and it can support dynamic configuration of both thin
|
||
|
|
clients and PCs.</p>
