Do not configure the same IP address to the network equipment in
the same network group. Each piece of equipment must be
assigned a unique IP address.
If the IP address is set [192.168.x.x], the Subnet Mask should be
set [255.255.255.0] for example.
The start address [xxx.xxx.xxx.0] and the last address
[xxx.xxx.xxx.255] of the IP address must not be assigned to any
other equipment. These address numbers are reserved.
The IP address must correlate to a network number. If network
numbers are different between the equipment, they cannot estab-
lish communications each other. In this case, the router is placed in
the networks to make the routing.
