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:
| Computer A | 192.168.40.1 |
| Computer B | 192.168.40.2 |
| Computer C | 192.168.40.10 |
| IB-21E/IB-22 printer | 192.168.40.20 |
