Class D is used for multicasting, in which one host sends messages to multiple hosts. (i.e. Video Conference via the internet)
Class E is used for research.
Comp TIA 6th editionCorrection to Class E:Class E addresses begin with 240 through 254 and are reserved for research.Class D IP addresses are used to multicasting to addresses (Sending to more than one address, without necessarily broadcasting.
Class E IP addresses are marked as experimental, and aren't used for anything other than that.
Class D and Class E IP addresses are not available for general use. Class D addresses begin with octets 224 through 239 and are used for multicasting, in which one host sends messages to multiple hosts, such as when the host transmits a video conference over the internet. Class E addresses begin with 240 through 254 and are reserved for research.
IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
First octet rule for each class:Class A: 0xxxxxxxClass B: 10xxxxxxClass C: 110xxxxxClass A range is 0 - 1270.0.0.0 and 127.0.0.0 are not "routable" IP addresses. One defines all networks and the other is the loopback. We have a total of 126 usable networks and 16,777,214 usable hostaddresses per network. There are even less if we don't count the private address of 10.0.0.0 (RFC 1918).Class B range is 128 - 191There are 16,384 total networks in this class; that's including the private addresses of 172.16.0.0 - 172.31.0.0 (RFC 1918). There are a total of 65,534 usable host addresses per network.Class C range is 192 - 223There are 2,097,152 total networks in this class; that's including the private addresses of 192.168.0.0 - 192.168.255.0 (RFC 1918). There are 254 usable hosts addresses per network.
In Internet Protocol version 4 (IPv4), an address beginning with a binary 1110. Class D addresses are reserved for multicast applications.

License? Where do you get this? In a Class B network there are 2 to the 16th power addresses. Class B = 255.255.0.0 65536 addresses In a Class A network there are 2 to the 24th power addresses Class A = 255.0.0.0 16,777,216 addresses In a class C network there are 2 to the 8th power addresses Class C = 255.255.255.0 256 addresses Class A around 16 million Class B around 65,000 Class C is actually 254 NOT 256. IP addresses are leased and therefore the lessee is given a license to use that particular IP address.
65,534
Class A for big corporations and Class B for universities.
How many possible host addresses are there in a Class A range?Class A range is 0 - 1270.0.0.0 and 127.0.0.0 are not "routable" IP addresses. One defines all networks and the other is the loopback. We have a total of 126 usable networks and 16,777,214 usable hostaddresses per network.
Classful addresses are no longer given out. Traditionally, this would require a Class B network, since it has a large enough range. A Class C network only has 256 addresses, but two adjacent Class C addresses would also work.Classful addresses are no longer given out.

A class B address range is all the addresses that start with binary 10, or decimal 128-192. As originally defined, the first two bytes (octets) indicate the network; the last two bytes are reserved for the host. That is, a class B network has about 65,000 available addresses.
A class C address.
APIPA addresses are in the range 169.254.0.1 through 169.254.255.254. These would be in the Class B address range.
They are private addresses. I think Class A
The number of possible IP address decreases as one steps down from Class A to Class C IP addresses because the availability of usable hosts. There is a decrease in the number of usable hosts from Class A to Class C IP addresses.
