Class C
192.0.0.1 to 223.255.255.254
NNN.NNN.NNN.HHH
Where:
NNN = Network identifier
HHH = Host identifier
Choosing IP Addresses
Two scenarios exist that will dictate the IP address assigned to your devices:
1. Connecting to an existing network
2. Establishing an independent network.
Connecting to an Existing Network
If your MS9500GL is to be connected into an existing network, you will need to contact the network administrator
and ask that a suitable address be allocated to you.
Establishing an Independent Network
If the MS9500GL is to be used on an independent network, you can assign an IP address of your choice. Follow
the guidelines below for choosing your IP address(es).
On an independent network you can (theoretically) use any addresses you wish. However, it is recommended that
you use the Class C format (i.e. from 192.0.0.1 up to 223.255.255.253).
Note: the MS9500GL will be delivered pre-configured with a class C IP address from the 192.0.0.? family.
Remember that there are two rules for choosing IP addresses:
The network identifier must be the same for each address,
The host identifier must be unique for each address.
Applying these rules to Class C addresses, it can be seen that the first three decimal values of your IP addresses
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
IP
Address
ESCAN PC:
208.132.180.41
MS9500GL Player 1
208.132.180.42
MS9500GL Player 2
208.132.180.43
The following is an example of an invalid Class C addressing scheme:
Device
IP
Address
ESCAN PC
208.132.180.41
MS9500GL Player 1
192.157.180.42
MS9500GL Player 2
209.100.123.43
Note: These are invalid because the network identifier for each address is not the same, even though each IP
Address is unique.
One more concept must be discussed in order to properly assign an IP address; that of the Subnet Mask.
