The addresses in the same network have different values in the network part.

(A) TRUE
(B) FALSE

FALSE is the correct answer. The addresses in the classful network have a structure with two parts: the network part and the host part.

Then, comparing any two IP addresses in one network, the following observations can be made:
1. The addresses in the same network have the same values in the network part.
2. The addresses in the same network have different values in the host part.
