IP ADDRESSING

 

The Internet

The Internet protocol suite consists of a well-defined set of

Protocol Suite

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 Gateway over the Network

To manage a device over the network, the Gateway must be correctly configured with the following IP information:

An IP address

A Subnet Mask

IP Addresses and Each device on your network must have a unique IP address to operate Subnet Masks 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.
