Not configured Network / Direct Attachment
If the IB-NAS2001 is attached to a not configured network where no DHCP server
provides the IP configuration (or the IB-NAS2001 is directly attached to the computer)
and the computers are configured to use DHCP (which is default setting) the IB-NAS2001
will activate its own DHCP Server with the default IP Address 192.168.0.1 and will
provide IP Addresses in a range from 192.168.1.2 till 192.168.1.50 with a net mask
4
of
255.255.255.0, which is part of the subnet
5
192.168.1.1-192.168.1.254. In this case the
IB-NAS2001 can be reached by typing “http://192.168.1.1” in the address line of a
standard web browser.
Network configured on fix IP-Addresses
In a network where no DHCP Server is present and all IP-Addresses are configured
manually and fixed for example between 192.168.1.1 and 192.168.1.254 with
255.255.255.0 as net mask, 192.168.1.1 as default gateway
6
and 192.168.1.1 as
DNS server you have to define the IP Address of the IB-NAS2001 also manually.
To configure the IP Address of the IB-NAS2001 to for example 192.168.1.100 please
start the SearchNAS.exe on the CD and proceed as follows:
Attention : If you are unable to run SearchNAS.exe on your computer because you
are not using a Windows operating system please configure the IP-
Address of the IB-NAS2001 using the web configuration interface as
described in point “Network Setting” on page 46.
Click on „Setup“

The net mask defines which part of the IP Address is describing the subnet. Together with the IP Address it is the minimum
necessary part of the network configuration. So it always has to be set appropriate.

TCP/IP based networks, as the internet, are structured into different network parts called sub nets. A subnet is built by a set
of IP Adresses all having the same digital beginning. Remember: an IP Address is always interpreted as 32 bit binary number
containing 32 binary digits. IP Adresses of the same subnet all have the left part of these digits in common. How many of those
digits are used to define a subnet is described by the net mask. Computers in the same subnet are able to communicate
directly together. Computers in different subnets need a so called router which connects different subnets and forwards the net
traffic from one subnet into another.
6
In a TCP/IP based Network a computer can send directly data only to other computers in it’s own subnet. To be able to send
data to other computers, a rooter is necessary to link this subnet to the rest of the network and all computers in the subnet
need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded.
This IP Address of the router is defined by the default gateway setting.
