The DHCP Mode option of the Network Configuration
Configure->NetworkConfig->DHCP-Mode
DHCP (Dynamic Host Control Protocol), is a mechanism by which a server
can automatically set the TCP/IP configuration on PC's and other computers.
This configuration includes not only the allocation of an IP Address,
but all aspects of the TCP/IP set up necessary to support correct operation
with the Server. The client applications still have to be configured, such
as Web Browser and e-mail programs.
The Server will configure the following fields in a PC's TCP/IP.
-
The IP Address of the PC.
-
The Netmask used on your LAN, as set up on the Server.
-
The DNS server address: this will be set to the IP address of the
Server
-
The Gateway Address: your Server is your gateway to the Internet,
so this field is set to the IP Address of the Server as well.
When DHCP is being used to configure IP Addresses, the Server must
be told what range of addresses it is allowed to serve. The default IP
address of the Server itself is "10.10.10.1" and the default Netmask
is "255.255.255.0". Potentially, this means that any PC can be given any
address between "10.10.10.2" and "10.10.10.254". If you have some devices
on you LAN that have already been assigned an IP address, you will probably
want to reduce this range to exclude your existing IP equipment.
Note: DHCP is turned OFF by default.
