installation
Installing an IP network is very complex and requires appropriate background knowledge because of many inter-
connected parameter and settings. Please contact your network administrator.
static and dynamic IP addresses and DHCP service:
Each device within an IP network needs its own IP address. In simple systems, all devices are located
within a local IP address range and within the same subnet. Thus, all devices can communicate with
each other without routing. Within home networks the scheme is as follows:
192.168 . xxx . xxx
subnet mask
The subnet mask divides the IP address into a network part (including the subnet) and into a host part
(individual number of a device within the subnet). For the scheme mentioned above the subnet mask is
always 255.255.255.0.
Why using static or dynamic IP addresses?
number of the subnet
defines the allocation to a subnet, must
be the same for all devices within one
subnet
individual number of the device in the
subnet
each device needs its own number for identifi-
cation This number must not be assigned
twice within one subnet.
Prefix for local IP address-
es according to class C of
the convention RFC 1918
