IP-address
The IP-address is the address, under which the connected device can be uniquely identified and
addressed in the network via the Ethernet interface card. It has to be choosen carefully, because
an IP-address allocated twice can cause network errors.
The IP-address consists of 4 parts: IP-address (xxx).(xxx).(xxx).(xxx)
Gateway
The Gateway IP-address is used, if the interface has to set up also a connection to devices in other
networks via a Gateway. All data blocks addressed to a device allocated to this other network will be
sent to the defined Gateway, which forwards them to the other network.
Netmask
The Netmask gets more and more significance in separated networks. The Netmask is used to
define which part of the IP-address is the networkaddress and which part od the IP-address is the
Host address. In the standard these borders are clearly defined (8/24 Class A, 16/16 Class B, 24/8
Class C).With subnettingt, it might be necessary to rearrange the Netmask. This can be done using
the parameter (# Host Bits).
If 0 is entered, the standard Netmask will be used. If a number between 1 and 31 is entered, then this
number indicates the number of bits from the right, that are 0. The Netmask is displayed in decimal
IP notation.
