IP Address
Enter an IP address for your phone. This IP address allows your phone to be reached by
other subscribers in your local network (e.g., PC).
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.
Please note:
– 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 (see example).
– 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.
Example:
Router IP address:
Network subnet mask
DHCP server address block
Possible IP addresses for the phone
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
Enter the IP address for the standard gateway through which the local network is con-
nected to the Internet. This is generally the local (private) IP address for your router/
gateway (e.g., 192.168.2.1). Your phone requires this information to be able to access
the Internet.
Preferred DNS Server
Enter the IP address for the preferred DNS server. DNS (Domain Name System) allows
you to assign public IP addresses to symbolic names. The DNS server is required to con-
vert the DNS name into the IP address when a connection is being established to a
server.
You can specify the IP address for your router/gateway here. This forwards address
requests from the phone to its DNS server.
There is no default setting for a DNS server.
Alternate DNS Server
Enter the IP address for the alternate DNS server that should be used in situations
where the preferred DNS server cannot be reached.
