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.
