the second operating mode, the device can retrieve an IP address for itself
from a DHCP server in the LAN.
Network without a DHCP server
In a network without a DHCP server, unconfigured LANCOM devices enable
their own DHCP server service when switched on and assign IP addresses,
information on gateways, etc. to other computers in the LAN (provided they
are set to automatic retrieval of IP addresses – auto DHCP). In this constella-
tion, the device can be accessed by every computer with the auto DHCP func-
tion enabled with a Web browser under IP address 172.23.56.254.
With the factory settings and an activated DHCP server, the device for-
wards all incoming DNS requests to the internal Web server. This
means that a connection can easily be made to set set up an uncon-
figured LANCOM by entering any name into a Web browser.
If the configuration computer does not retrieve its IP address from the
LANCOM DHCP server, it determines the current IP address of the computer
(with Start
Run
dows 2000 or Windows XP or Windows Vista, with Start
command winipcfg at the prompt under Windows Me or Windows 9x, or
with command ifconfig in the console under Linux). In this case, the LANCOM
can be accessed with address x.x.x.254 (the "x"s stand for the first three
blocks in the IP address of the configuration computer).
