The IP address must be unique for each device on the network.
The Network mask must be the
same for all devices on the network. This value is also known as Subnet
mask.
The Default gateway is usually the same for all devices on the network.
Start by entering ipconfig at the command
line of your host computer. This command displays network settings
of the Ethernet adapters on the host computer. Look for the settings
of the Ethernet adapter that is connected to the target hardware.
Suppose that the Ethernet adapter connected to the target hardware has the following values:
IPv4 Address. . . . . . . . . . . : 192.168.1.2 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1
In that case, for the target hardware:
Set IP address to an unused IP
address, between 192.168.1.3 and 192.168.1.254
Set Network mask to use the same
network mask value, 255.255.255.0
