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 ES9600 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 ES9600 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 ES9600 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
ES9600 Player 1 208.132.180.42
ES9600 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
ES9600 Player 1 192.157.180.42
ES9600 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.
The Subnet Mask
The Subnet Mask is another 32-bit binary number that is used to 'mask' certain bits of the IP Address. This
provides a method of extending the number of network options for a given IP Address. It works by allowing part
of the host identifier to be used as a 'subnet identifier'.
