Question
The number of addresses in a class B block is _______.
a. 256
b. 65,536
c. 16,777,216
d. 1024
Solution
The number of addresses in a class B block is 65,536. So, the correct answer is b. 65,536.
Here's the step by step explanation:
In a Class B address, the first two octets are used for network ID and the last two octets are used for host ID.
Each octet is composed of 8 bits. Since two octets are used for host ID, that means there are 16 bits available for host addresses (8 bits per octet * 2 octets = 16 bits).
The number of addresses that can be represented with 16 bits is 2^16, which equals 65,536.
Therefore, a Class B block can have
