A. B. C. D. E.


Private IPv4 addresses are non-routable addresses, meaning that they are not intended to be used on the internet, and are instead reserved for use on private networks. These addresses are defined in RFC 1918 and include three ranges:


The benefits of using private IPv4 addresses are as follows:

  1. They are less costly than public IP addresses: Since private IP addresses are not intended to be used on the internet, they are not subject to the same rules and regulations that apply to public IP addresses. This means that organizations can use private IP addresses without having to pay for them, which can result in significant cost savings.

  2. They can be assigned to devices without Internet connections: Since private IP addresses are not used on the internet, they can be used on devices that do not need internet connectivity. This includes devices on a local network such as printers, servers, and routers, which can all be assigned private IP addresses.

On the other hand, the options A, D, and E are not correct.

A. They are routed the same as public IP addresses: Private IP addresses are not routable on the internet and are instead intended for use on private networks. They cannot be routed the same way as public IP addresses.

D. They eliminate the necessity for NAT policies: While NAT (Network Address Translation) can be used to translate private IP addresses to public IP addresses, it is not eliminated altogether. NAT is still necessary to allow devices with private IP addresses to access the internet.

E. They eliminate duplicate IP conflicts: While private IP addresses reduce the likelihood of duplicate IP conflicts on the internet, they do not eliminate them entirely. Duplicate IP addresses can still occur on a private network if two devices are assigned the same IP address.
