IP Addressing
The Internet Protocol Suite
The Internet protocol suite consists of a well-defined set of communications protocols and several standard
application protocols. Transmission Control Protocol/Internet Protocol (TCP/IP) is probably the most widely
known and is a combination of two of the protocols (IP and TCP) working together. TCP/IP is an internation-
ally adopted and supported networking standard that provides connectivity between equipment from many
vendors over a wide variety of networking technologies.
Managing the Router over the NetworK
To manage a device over the network, the Router must be correctly configured with the following IP informa-
tion:
An IP address
A Subnet Mask
IP Addresses and Subnet Masks
Each device on your network must have a unique IP address to operate correctly. An IP address identifies
the address of the device to which data is being sent and the address of the destination network. IP ad-
dresses have the format n.n.n.x where n is a decimal number between 0 and 255 and x is a number between
1 and 254 inclusive.
However, an IP Address alone is not enough to make your device operate. In addition to the IP address, you
need to set a subnet mask. All networks are divided into smaller sub-networks and a subnet mask is a num-
ber that enables a device to identify the sub-network to which it is connected.
For your network to work correctly, all devices on the network must have:
The same sub-network address.
The same subnet mask.
The only value that will be different is the specific host device number. This value must always be unique.
An example IP address is ‘192.168.10.8’. However, the size of the network determines the structure of this
IP Address. In using the Router, you will probably only encounter two types of IP Address and subnet mask
structures.
Type One
In a small network, the IP address of ‘192.168.10.8’ is split into two parts:
Part one (‘192.168.10’) identifies the network on which the device resides.
Part two (‘.8’) identifies the device within the network.
This type of IP Address operates on a subnet mask of ‘255.255.255.0’.
