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
Cable/DSL Gateway
over the Network
To manage a device over the network, the Cable/DSL Gateway 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 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 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 ‘192.168.100.8’. However, the size of the network
determines the structure of this IP Address. In using the Gateway, you will
probably only encounter two types of IP Address and subnet mask structures.
Type One
In a small network, the IP address of ‘192.168.100.8’ is split into two parts:
■
Part one (‘192.168.100’) identifies the network on which the device resides.
■
Part two (‘.8’) identifies the device within the network.
