IP Addresses Reserved for Private Networks
RFC 1918 reserves IP addresses in the following ranges to be used for private networks.
10.0.0.0 – 10.255.255.255 (Class A)
172.16.0.0 – 172.31.255.255 (Class B)
192.168.0.0 – 192.168.255.255 (Class C)
Multicast IP Addresses
Multicast IP Addresses are used in multicasting, a technique that allows delivery of a single
packet of data to multiple nodes on the network. Any node that joins a Multicast group will
respond to the Multicast IP address assigned to that group. Subsequently, any data sent to that
Multicast IP address may be received by all nodes which are members of that Multicast group.
Multicast (Class D) IP addresses (224.0.0.0 through 239.255.255.255) are reserved by the Internet
authorities for multicasting.
Multicasting is a feature of Ethernet Global Data. For more information on the use of
multicasting in Ethernet Global Data, see the topic “Group Usage” in the chapter: “Ethernet
Global Data”.
