Class B IP addresses are used for medium and large-sized networks in enterprises and organizations. They support up to 65,000 hosts on 16,000 individual networks. These support up to 256 hosts on each of 2 million networks. Class D and E addresses are least used.
Who owns the Class A IP addresses?

Class B Network The first 16 bits (known as two octets) help you identify the network. The other remaining 16 bits indicate the host within the network. An example of Class B IP address is 168.212. 226.204, where *168 212* identifies the network and *226.204* helps you identify the Hut network host.

What are the five different classes of IP addresses?
TCP/IP defines five classes of IP addresses: class A, B, C, D, and E . Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses from the first three classes (A, B and C) can be used for host addresses.
Which is a Class B IP address?
Class B addresses are IP addresses that are assigned to network devices, such as computers, and include all addresses in which the first two bits of the first octet are 10. This includes all values from 10000000 to 10111111, or 128 to 191.
Why are IP addresses divided into classes?
1 Answers. IP addresses are divided into classes so that they can be assigned to a particular business, government or other entity based on size and need. There are five IP classes plus certain special addresses: Default Network – The IP address of 0.0.0.0 is used for the default network.

An IP address consists of two parts, one identifying the network and one identifying the node, or host. The Class of the address determines which part belongs to the network address and which part belongs to the node address. All nodes on a given network share the same network prefix but must have a unique host number.
