What is a characteristic of private IPv4 addressing?

Answer options

• A. provides unlimited address ranges
• B. is used when the network has multiple endpoint listeners
• C. reduces network complexity
• D. alleviates the shortage of IPv4 addresses

Correct answer: D

Explanation

The correct answer is D because private IPv4 addressing helps to alleviate the shortage of public IPv4 addresses by allowing organizations to use non-routable addresses internally. Options A and B are incorrect as they do not accurately describe the nature of private IPv4 addressing, and C is misleading since private addressing can sometimes complicate network design rather than simplify it.
