Network without DHCP server
In a network without DHCP server, unconfigured LANCOM devices activate
their own DHCP server service after starting, and assign appropriate IP
addresses and gateway information to the other workstations within the LAN,
provided that the workstations are set to obtain their IP address automatically
(auto-DHCP). In this constellation, the device can be accessed with any web
browser from each PC with activated auto-DHCP function through the name
LANCOM
or by its IP address
172.23.56.254
.
If the configuration PC does not obtain its IP address from the LANCOM DHCP
server, figure out the current IP address of this PC (with
Start
Execute
cmd
and command
ipconfig
at the prompt under Windows 2000 or Windows
XP, with
Start
Execute
cmd
and the command
winipcfg
at the prompt
under Windows Me and Windows 9x, or with the command
ifconfig
on the
console under Linux). In this case, the LANCOM is reachable under the IP
address
x.x.x.254
( “x” stands for the first three blocks in the IP address of
the configuration PC).
Network with DHCP server
If a DHCP server is active in the LAN to assign IP addresses, an unconfigured
LANCOM device will turn off its own DHCP server. It will change into DHCP
client mode and will obtain an IP address from the DHCP server of the LAN.
This IP address is not known at first. The accessibility of the device depends
on the name resolution:
If there is a DNS server for name resolution in the LAN, which inter-
changes the assignment of IP addresses to names with the DHCP server,
then the device can be accessed by the name “LANCOM <MAC address>”
(e.g. “LANCOM-00a057xxxxxx”).
