Correct answer: A
To determine the class of the IP address 123.23.156.4, we examine the first octet (the first number), which is 123.
In classful addressing, the class is determined by the range of the first octet:
Class A: 1 – 126
Class B: 128 – 191
Class C: 192 – 223
Class D: 224 – 239
Since 123 is within the range 1 – 126, the IP address belongs to Class A.
