4 How to Set Up TCP/IP

4.1 Introduction

Before you set up a TCP/IP network with addressing, it's important to understand all the
terms involved. The following glossary explains network terminology.

4.1.1 Glossary

Network: A group of interconnected components, such as a central computer, network
switching equipment, and other computers or devices.
TCP/IP network: A network made of a computer, network switching equipment, and other
network devices such as network PIP cards plugged into power amps that communicate
using TCP and IP protocols.
Subnet: A small network within a larger network. For example, a control network might be
a subnet of a venue's network, which could include computers throughout the building. Or
an audio network might be divided into subnets. For example, one audio subnet might be
for the house system and another audio subnet might be for the paging system.
IP address: An identifier for a computer or device on a TCP/IP network. Each device in a
network has its own IP address to identify it. Example: 126.126.17.42. Networks using the
TCP/IP protocol route messages based on the IP address of the destination. An IP address
is made of four numbers separated by periods. Each number can be zero to 255. Typically
the last number should never be a zero or 255. For example, 126.126.17.1 could be an IP
address. 126.126.17.0 would not be a typical IP address.
A TCP/ IP or IP address has two parts: the NETWORK ID and the HOST ID. The NETWORK
ID identifies the network, and the HOST ID identifies either the subnet and device, or just
the device if there is no subnet.
The subnet mask is a code that indicates which part of the TCP/IP address is the NET-
WORK ID and which part is the HOST ID. In subnet-mask code, 255 means "This part of the
address is the NETWORK ID".
Example:
Suppose the IP ADDRESS of a device is 126.126.17.42
and the SUBNET MASK is 255.255.0.0.
That means, (126.126) is the NETWORK ID. The remaining set of numbers (17.42) is the
HOST ID.
