Appendix D: Utilizing IP Addresses on a Local Network

Introduction
Access to the Internet is achieved via Internet IP addresses. Currently, IP addresses are limited.
There are five classes of networks, and each network contains IP addresses. A network can only hold
a limited number of IP addresses, and the number of IP addresses depends on the network class.
The five classes are labeled "A" through "E," with the most common one being the "C"-class network.
IP Construction and Network Class
IP Construction

Network Class A Class: A network that contains IP addresses from 0 to 127 at room "X1." Network
ID: X1Host ID: X2, X3, X4 There are 128 A-Class networks in the world.
B Class: A network that contains IP addresses from 128 to 172 at room "X1." Network ID: X1, X2Host
ID: X3, X4There are 65,534 B-Class networks in the world.
C Class: A network that contains IP addresses from 192 to 223 at room "X1." Network
ID: X1, X2, X3Host ID: X4 The most common network; there are 2,097,152 C-class
networks in the world.
D Class: A network that contains IP addresses from 224 to 239 at room "X1." D-class networks are
used for multicasting, and are not allowed for common use.
E Class: A network that contains IP addresses from 240 to 255 at room "X1." E-class networks are
reserved.
Improve the lighting conditions. If this doesn't help and
the lighting conditions within the installation area can not
be improved, consider replacing the basic lens with a
more sensitive lens. Set the quality/bit rate to a higher
value.
Open the display properties on your desktop and
configure your display to show at least 65,000 colors;
i.e., at least 16-bit.
NOTE: Using only 16 or 256 colors on your computer
will produce dithering artifacts in the image. Adjust the
camera lens manually.
