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
cmd
and command
ipconfig
at the prompt under Win-
dows 2000 or Windows XP or Windows Vista, with
Start
Run
cmd
and
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).
