Network without a DHCP server

In a network without a DHCP server, unconfigured 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 constellation, the device can be accessed by every computer with the auto DHCP function enabled with a web browser under IP address 172.23.56.254.

Note: With the factory settings and an activated DHCP server, the device forwards all incoming DNS requests to the internal web server. This means that a connection can easily be made to set up an unconfigured device by entering any name into the address bar of a web browser.

If the configuration computer does not retrieve its IP address from the DHCP server, determine the current IP address of the computer (with Start > Run > cmd and command ipconfig at the prompt under Windows 7 or higher, or with command ifconfig in the CLI under Linux). In this case, the device 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).
