9-4 Basics of IP Addressing
• Maximum of 28 or 254 node addresses
• Class D
• Range is 224.0.0.0 to 239.255.255.255
• Used for multicast packets (i.e., host sends out router discovery packets to
learn all of the routers on the network)
• Class E
• Range is 240.0.0.0 to 255.255.255.255
• Reserved for future use
Note: Class D & E should NOT be assigned to net assignment of IP addresses.
In addition, the first octet, 127, is reserved. In each network definition, the
first node number (i.e., "0") is used to define the network, as well as the
last number (i.e., "255"). The last number is known as the broadcast
address.
Note: Non-public addresses can include a network address assigned from the
network administrator or from the IP provider. Also, there is one network in
each class that is defined for private use, allowing the creation of
internal networks. These addresses are Class A: 10.0.0.0, Class
B:172.10.0.0, and Class C: 192.0.2.0.
