A TCP and IP settings
A.1 Introduction
Before installing a wireless network device you must analyze your the
network environment. The information in this appendix is only helpful in
determining which information is needed for a proper installation of such
a device.
This appendix explains how devices in a network are identified in order
to communicate with each other. Chapter 3: ‘Configuring the Access
Point’ on page 21 contains the instructions on how to apply this
information to your situation
A.2 How do computers communicate in a network
Computers use protocols to communicate to each other. The protocol
that is used between computers (and other network devices) that are
connected to the internet is TCP/IP (Transmission Control Protocol/
Internet Protocol). This is also the main protocol in many other computer
networks.
The internet resembles the telephone network to some extent. Like a
phone number that uniquely identifies one telephone connection, IP
addresses are used to determine to which computer the data must be
sent. An IP address looks like this: 192.168.201.160. Each of the four
groups is represented in the computer by one byte, so only numbers
from 0 to 255 can be used for a group.
IP addresses are meant to be unique world-wide. To achieve this, IP
addresses are assigned (you can’t just start using random addresses,
but you have to ask for them). Usually, your Internet Service Provider will
assign you a IP address range you can use.
