How can I assign IP addresses properly?
The Internet Protocol address is a unique number that represents a specific computer in a network. Format of the IP Address is four numbers separated by dots, e.g. '192.168.110.171.' Each number should be decimal of 0 through 255.
The IP address is compiled from 'network ID + user ID.' This results in three different IP address 'classes.' Representing the network ID as 'n' and the user ID as 'u,' each class has the following attributes:
Class IP Addressing First Segment Range Application Number of Networks Number of Users A n.u.u.u 0 <127 Large scale network 126 16,777,214 B n.n.u.u 128 <191 Mid scale network 16,384 65,634 C n.n.n.u 192 <223 Small network 2,097,150 254
For example, in a class C network, you can assign an IP address as '192.168.40.1.'
Devices having IP addresses with different network IDs ('n' above) cannot communicate even when they are in the same network segment.
Following is an example of a Class C IP network with 3 computers and 1 IB-21E/IB-22 printer:
