Printer IP Address,

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. ‘’ 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:

ClassIP AddressingFirst Segment RangeApplicationNumber of NetworksNumber of Users
An.u.u.u0<127Large scale network12616,777,214
Bn.n.u.u128<191Mid scale network16,38465,634
Cn.n.n.u192<223Small network2,097,150254

For example, in a class C network, you can assign an IP address as ‘’

  • 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 A192.168.40.1
Computer B192.168.40.2
Computer C192.168.40.10
