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 network 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 example 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.

IP Address Comment
123.234.45.211 Valid.
123.234.45.213 Valid. The first three numbers match the previous IP address. The fourth number
must be a unique number in the range of 1 to 254.
123.202.45.214 Invalid. Second number does not match the previous IP addresses. The first three
numbers must match on all IP addresses with subnet mask 255.255.255.0.
123.234.45.0 Invalid. The first three numbers are valid but the fourth number cannot be 0.
123.234.45.255 Invalid. The first three numbers are valid but the fourth number cannot be 255.
