The most common IP address classes are:
Class Name
Class A
Class B
Class C
refers to the network identifier and
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:
• Network identifier must be the same for each IP address
Host identifier must be unique for each address.
•
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 DVI Pro switcher
NOTE: The host identifiers (41 and 42 in the example above) do not need to be
sequential or in any particular order. However, it is recommended that you group the
numbers for simplicity.
The following is an example of an invalid Class C addressing scheme:
Device
Matrix Switcher Control Software computer
DXP DVI Pro switcher
NOTE: The above addresses are invalid because the network identifier for each address
is not the same even though each IP address is unique.
You can perform a test from your computer to check that a device at a particular address is
responding correctly or to determine its address (see "Pinging for the IP Address").
Valid Address Range
0.0.0.1 to 127.255.255.254
128.0.0.1 to 191.255.255.254
192.0.0.1 to 223.255.255.254
refers to the host identifier.
