'auto': The server is in automode. In this mode, after switching it on, the
device looks for other DHCP server within the local network. This search
can be recognized by the Tx LED flashing momentarily after activation.
The device then disables its own DHCP server if any other DHCP
servers are found. This prevents the unconfigured device from
assigning addresses not in the local network when switched on.
The device then enables its own DHCP server if no other DHCP
servers are found.
Whether the DHCP server is active or not can be seen in the DHCP
statistics.
The default state is 'auto'.
6.4.3 How are the addresses assigned?
IP address assignment
Before the DHCP server can assign IP addresses to the computers in the
network, it first needs to know which addresses are available for assignment.
Three options exist for determining the available selection of addresses:
The IP address can be taken from the address pool selected (start address
pool to end address pool). Any valid addresses in the local network can
be entered here.
If '0.0.0.0' is entered instead, the DHCP server automatically determines
the particular addresses (start or end) from the IP or Intranet address
settings in the 'TCP-IP-module' using the following procedure:
If only the IP address or only the Intranet address is entered, the start
or end of the pool is determined by means of the associated network
mask.
If both addresses have been specified, the Intranet address has
priority for determining the pool.
From the address used (IP or Intranet address) and the associated
network mask, the DHCP server determines the first and last possible IP
address in the local network as a start or end address for the address
pool.
If the router has neither an IP address of its own nor an Intranet address,
the device has gone into a special operating mode. It then uses the IP
address '10.0.0.254' for itself and the address pool '10.x.x.x' for the
assignment of IP addresses in the network. In this state, the DHCP server
