4.2 TCP/IP Addressing Rules

In the next section, you will be assigning static TCP/IP addresses to the devices in your
network. When you do so, be sure to follow the addressing rules below. Otherwise, the
computer may not communicate with the devices.
1. Turn off DHCP (automatic addressing).
2. Assign each device a static (fixed) IP address. An IP address is made of four numbers
separated by periods. Each number can be zero to 255.
3. Make sure that the computer and all the devices have the same NETWORK IDs in their
addresses. This tells the computer that all those devices are on the same network. Various
tools are available to determine whether devices are on the same network. In the addressing
utility described later, if items are NOT on the same network, they are highlighted in the list.
4. Make sure that each component has its own TCP/IP address, and there are no duplicate
addresses. The same holds true for IQ addresses.
5. Assign a subnet mask. Make it the same for all devices on the network. If the network you
are assembling will interconnect with other networks, your network is considered to be a
subnet within the larger network. Check with the network administrator to determine the
proper Subnet Mask for your subnet.
If you have a stand-alone network, you may use a Subnet Mask of 255.255.0.0 for all com-
ponents, including the computer.
Note: Just because two components have the same subnet mask does not mean that they
are on the same network. As we said, the subnet mask just tells what part of the TCP/IP
address is the Network ID.
