There are three
LAN parameters
that can be modified and adjusted
specifically to match your network setting; These are described below.
Consult your network administrator for the setting that will best suit
your application.
IP address - The unique, computer-
readable address of a device
on your network. An IP address typically is represented as four
decimal numbers separated by periods (for example,
192.160.0.233). Refer to the next section -
Choosing a Static IP
Address.
Subnet mask -
A code that helps the network device determine
whether another device is on the same network or a different
network.
Gateway IP - The IP address of a device that act
s as a gateway,
which is a connection between two networks. If your network
does not have a gateway, set this parameter to 0.0.0.0.
Choosing a Static
IP
Address
For a Network Administered by a Network Administrator
If you are adding the Ethernet device
to an existing Ethernet network,
you must choose IP addresses carefully. Contact your network
administrator to obtain an appropriate static IP address for your
Ethernet device. Also have the network administrator assign the
proper subnet mask and gateway
IP.
For a Network without a Network Administrator
If you are assembling your own small Ethernet network, you can
choose your own IP addresses. The format of the IP addresses is
determined by the subnet mask. You should use the same subnet
mask as the computer you are using with your Ethernet device. If your
subnet mask is 255.255.255.0, the first three numbers in every IP
address on the network must be the same. If your subnet mask is
255.255.0.0, only the first two numbers in the IP addresses on the
networ
k must match.
For either subnet mask, numbers between 1 and 254 are valid
choices for the last number of the IP address. Numbers between 0
and 255 are valid for the third number of the IP address, but this
number must be the same as other devices on your network if your
subnet mask is 255.255.255.0.
Table 2-
1 shows examples of valid and invalid IP addresses
for a network using subnet mask 255.255.255.0. All valid IP
addresses contain the same first three numbers. The IP
addresses in this table are for examp
le purposes only. If you
are setting up your own network, you probably do not have a
gateway, so you should set these values to 0.0.0.0.
