Which private IP addresses can I use in my network?

In principal there are 3 private address ranges that can be used. These ranges

are defined in RFC 1918. These addresses are private because they are not

globally assigned.

It is common for organizations to divide it into smaller /16 or /24 networks.

A /24 network for example has the range 192.168.1.0 ... 192.168.1.255 and

has therefore 254 hosts.

A second set of special networks is the Link-Local Address (APIPA or Auto IP)

range. These ranges are defined in RFC 3330 and RFC 3927:

169.254.0.0

255.255.0.0

What is most done wrong, when connecting a GigE camera to a network is

the usage of different network masks for the IP devices (that is GigE camera

and PC with Gigabit Ethernet network card).

Example of 2 hosts in different networks (Host1 could be a GigE camera,

Host2 could be PC or laptop):

IP address range Networks Description

10.0.0.1 ... 10.255.255.254

255.0.0.0

1 class A network

For more information see:

RFC 1918

172.16.0.01 ... 172.31.255.254

255.240.0.0

16 class B networks

192.168.0.1 ... 192.168.255.254

255.255.0.0

256 class C networks

Table 11: Private IP addresses

Host IP address Description

Host1 192.168.0.1

255.255.255.0

In this example you can see:

Host2 is in a different network compared to Host1.

Therefore Host1 and Host2 cannot communicate with each

other.

Solution: Take care that both hosts are in same network:

• Either set third number of Host1 from 0 to 1 or

• Set third number of Host2 from 1 to 0.

Host2 192.168.1.2

255.255.255.0
