Network administration
IP address
Enter an IP address for your device. This IP address allows your device to be reached by other
subscribers in your local network.
The IP address comprises four individual groups of numbers with decimal values from 0 to 255
that are separated by a dot, e.g., 192.168.2.1.
The IP address must be included in the address block used by the router/gateway for the local
network. The valid address block is defined by the IP address for the router/gateway and the
Subnet mask.
The IP address must be unique across the network, which means that it must not be
used by another device connected to the router/gateway.
The fixed IP address must not belong to the address block that is reserved for the
DHCP server for the router/gateway.
Check the settings on the router or ask your network administrator.
Subnet mask
The Subnet mask specifies how many parts of an IP address the network prefix must comprise.
For example, 255.255.255.0 means that the first three parts of an IP address must be the same for
all devices in the network, while the last part is specific to each device. In subnet mask
255.255.0.0, only the first two parts are reserved for the network prefix.
Enter the subnet mask that is used by your network.
Standard gateway
The Standard gateway is generally the router/gateway of the local network. Your Integrator/
DECT manager device requires this information to be able to access the Internet.
Enter the local (private) IP address for the standard gateway through which the local network
is connected to the Internet (e.g., 192.168.2.1).
Preferred DNS
DNS (Domain Name System) allows you to assign public IP addresses to symbolic names. The
DNS server is required to convert the DNS name into the IP address when a connection is being
established to a server.
Enter the IP address for the preferred DNS server. You can specify the IP address for your
router/gateway here. This forwards address requests from the Integrator/DECT manager to
its DNS server. There is no default setting for a DNS server.
Alternate DNS
Enter the IP address for the alternate DNS server that should be used in situations where the
preferred DNS server cannot be reached.
