	Table 36 IP address classes

	Class	Range	Description

	C	192 to 223	This is used for smaller networks having fewer than
			255 nodes, such as smaller colleges and businesses
			(for example, 195.10.107.0).

Two additional address classes exist. Class D addresses support IP multicasting, which is used to transmit packets to multiple IP addresses. Class E addresses are reserved for Internet engineering task force experimental use.

Network address 127 is not a valid network number. It is used for testing purposes only.

The EIU supports Ethernet connectivity to class A, B or C networks.

The following diagrams show addressing and subnet mask examples of

Network classes.
