Explanation

In IP networking, the "class" of an IP address refers to the range of values in the address and how many bits are used to identify the network and the host. Class B addresses are IP addresses that are assigned to networks that have a large number of devices. Class B IP addresses use the first 16 bits to identify the network and the remaining 16 bits to identify the host.

The host bit in Class B address is 16 bits

This means that class B addresses have a range of 128.0.0.0 to 191.255.255.255, and there are 16,384 (214) possible networks and 65,534 (216-2) possible host addresses per network.
