What is a characteristic of private IPv4 addressing?

Answer options

• A. is used when the ISP requires the new subnet to be advertised to the internet for web services
• B. provides unlimited address ranges
• C. is used when the network has multiple endpoint listeners

Correct answer: D

Explanation

The correct answer is D because private IPv4 addressing allows organizations to use a range of addresses that are not routable on the internet, helping to alleviate the overall shortage of available IPv4 addresses. Options A, B, and C do not accurately describe the function or purpose of private IPv4 addressing, as they either misrepresent its usage or suggest incorrect advantages.
