A TCP and IP settings
A.1 Introduction
Before installing a wireless network device you must analyze your
network environment. The information in this appendix is helpful in
determining which information is needed for a proper installation of such
a device. It also provides a brief description of a typical home
installation.
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 worldwide. 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 an IP address or
IP address range you can use.
