VN-MATRIX User Guide    Appendix A: Guide to IP Addressing 
I458GB issue 6    Page 125 
What is an IP Address? 
A full explanation of IP addressing is beyond the scope of this user guide. However the following 
details will provide you with enough information to get started. 
An IP Address is a 32-bit binary number that is used to identify each device on an Ethernet network. 
This number is usually represented by four decimal numbers (each in the range 0 to 255) separated 
by dots, e.g. 198.123.34.240. This is called ‘dotted decimal notation’. 
An IP Address is divided into two parts: 
•  the ‘network identifier’, and 
•  the ‘host identifier’. 
On a given network each address must have the same network identifier value but have a unique host 
identifier. There are, therefore, different ‘classes’ of address which define: 
•  the range of valid addresses, and 
•  which parts of the address are used for the network and host identifiers. 
The most common IP Address classes are: 
Class Name  Valid Address Range  Identifier Arrangement* 
Class A  0.0.0.1 to 127.255.255.254  NNN.HHH.HHH.HHH 
Class B  128.0.0.1 to 191.255.255.254  NNN.NNN.HHH.HHH 
Class C  192.0.0.1 to 223.255.255.254  NNN.NNN.NNN.HHH 
*Where:NNN = Network identifier 
HHH = Host identifier 
Private & Public Address Ranges 
Within each of the above classes are a range of addresses designated as ‘private’ addresses. These 
are addresses which should only ever be used on private local networks and intranets and cannot be 
accessed directly from the internet. 
10.0.0.0 – 10.255.255.255 
172.16.0.0 – 172.31.255.255 
169.254.0.0 –169.254.255.255 
192.168.0.0 – 192.168.255.255 
All other addresses outside these ranges are considered ‘public’ addresses. 
Multicast Address Range 
A further range of addresses are available for multicast usage: 
224.0.0.0 – 239.255.255.255 
These addresses (also known as Class D addresses) are used to allow several devices to be part of 
the same multicast group. Each device in the group has the same multicast address and can 
effectively send data to all other devices in the same group simultaneously.
