Network Setup

What is an IP Address?

An IP address is a 32-bit binary number that is used to identify each device on an Ethernet
network. This number is usually represented by four decimal numbers (called "octets"), each
in the range of 0 through 255 and separated by dots; for example, 198.123.34.240. This is
called "dotted decimal notation."
An IP address is divided into two parts:
•
•
Each address on a given network must have the same network identifier value but have a
unique host identifier. As a result, there are different classes of addresses that define the
range of valid addresses and the parts of the address that are used for the network and
host identifiers.
The most common IP address classes are:
Class Name
Class A
Class B
Class C
NNN

Choosing IP Addresses

If the computer and the DXP are directly connected or connected via their own independent
network, follow the guidelines below for choosing the IP addresses.
However, if you intend to connect your computer and switcher to an existing network, you
need to advise the network administrator and ask the administrator to allocate suitable IP
addresses.
On an independent network, it is generally recommended that you use the Class C format
(from 192.0.0.1 to 223.255.255.254).
There are two rules for choosing IP addresses:
•
•
Applying these rules to Class C addresses, the first three decimal values of your IP address
must all be the same while the last value is used to uniquely identify each device.
The following is an example of a valid Class C addressing scheme:
Device
Matrix Switcher Control Software computer
DXP HD 4K switcher
NOTE: The host identifiers (41 and 42 in the above example) do not need to be

numbers for simplicity.
