Which of the following are common classes of IP addresses?

The correct answer identifies common classes of IP addresses that are foundational to understanding how networks manage communications across devices.

Class A, Class B, Class C, Class D, and Class E represent the traditional segmentation of IP addresses into different categories based on their leading bits and the intended purpose of each class.

• Class A addresses are designed for very large networks with a leading bit of 0, allowing for a vast number of host addresses.

• Class B addresses, with a leading bit of 10, serve medium-sized networks, providing a balance between the number of networks and hosts per network.

• Class C addresses, starting with 110, are reserved for smaller networks and have a higher number of networks with fewer hosts due to their structure.

• Class D addresses are utilized for multicast groups, enabling the transmission of data to multiple devices simultaneously.

• Class E addresses, designated for experimental purposes, are not commonly used in standard routing but demonstrate the potential for future applications.

The other choices do not conform to recognized classifications of IP addresses according to the standard IPv4 structure. Classes beyond E, or numerical classifications that do not correspond to established schemes, do not play a role in the fundamental architecture of IP networking. This makes the identification of classes A through
