OGU 930500105-A1
The crossed-out wheeled bin symbol on this electric or electronic equipment, or on its
packaging, indicates that, at the end of its life, it must not be disposed of as unsorted
household waste. Instead it must be separately collected.
As a consumer you must, therefore, use the specific collection schemes and, in partic-
ular, the municipal collection schemes provided for waste electrical and electronic
equipment.
The separate collection and appropriate treatment of the equipment at the time of dis-
posal helps to conserve natural resources and to ensure that it is recycled in a manner
that protects human health and the environment from materials, components and sub-
stances that can be dangerous to the environment and harmful to human health.
Furthermore, the separate collection and appropriate treatment of the equipment, at
the time of disposal, facilitates its possible reuse or possible materials recovery.

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 internationally
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 information:
•
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 addresses 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 inclu-
sive.
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 number
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 struc-
tures.
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’.
Type Two

In larger networks, where there are more devices, the IP address of ‘192.168.10.8’ is, again, split into two parts
but is structured differently:
•
Part one (‘192.168’) identifies the network on which the device resides.
•
Part two (‘.10.8’) identifies the device within the network.
This type of IP Address operates on a subnet mask of ‘255.255.0.0’.
How does a Device Obtain an IP Address and Subnet Mask?
There are three different ways to obtain an IP address and the subnet mask. These are:
•
Dynamic Host Configuration Protocol (DHCP) Addressing
•
Static Addressing
•
Automatic Addressing (Auto-IP Addressing)
DHCP Addressing
The Router contains a DHCP server, which allows computers on your network to obtain an IP address and sub-
net mask automatically. DHCP assigns a temporary IP address and subnet mask which gets reallocated once
you disconnect from the network.
DHCP will work on any client Operating System. Also, using DHCP means that the same IP address and subnet
mask will never be duplicated for devices on the network. DHCP is particularly useful for networks with large
numbers of users on them.
Static Addressing
You must enter an IP Address and the subnet mask manually on every device. Using a static IP and subnet
mask means the address is permanently fixed.
Auto-IP Addressing
Network devices use automatic IP addressing if they are configured to acquire an address using DHCP but are
unable to contact a DHCP server. Automatic IP addressing is a scheme where devices allocate themselves an
IP address at random from the industry standard subnet of 169.254.x.x (with a subnet mask of 255.255.0.0). If
two devices allocate themselves the same address, the conflict is detected and one of the devices allocates
itself a new address. Automatic IP addressing support was introduced by Microsoft in the Windows 98 operating
system and is also supported in Windows 2000 and Windows XP.
