Automatic address administration with DHCP
In order to operate smoothly in a TCP/IP network, all the devices in a local
network must have unique IP addresses.
They also need the addresses of DNS server and NBNS server as well as that
of a default gateway through which the data packets are to be routed from
addresses that are not available locally.
In a smaller network, it is still conceivable that these addresses could be
entered manually in all the computers in the network. In a larger network
with many workstation computers, however, this would simply be too great.
In such situations, the DHCP (Dynamic Host Configuration Protocol) is the
ideal solution. Using this protocol, a DHCP server in a TCP/IP-based LAN can
dynamically assign the necessary addresses to the individual stations.
4.4.1
The DHCP server
As a DHCP server, the
ELSA LANCOM Wireless L-11
can administer the IP
addresses in its TCP/IP network. In doing so, it passes the following
parameters to the workstation computers:
IP address
Netmask
Broadcast address
DNS server
NBNS
Default gateway
Period of validity for the parameters assigned
The DHCP server takes the IP addresses either from a freely defined address
pool or determines the addresses automatically from its own IP address (or
intranet address).
