A. B. C. D. E.


Private IPv4 addresses are a range of IP addresses that can be used within a private network, without the need for coordination with the Internet Assigned Numbers Authority (IANA), which manages the distribution of public IP addresses. Private IP addresses are not routable over the public internet and are intended for use within a private network.

The benefits of private IPv4 addresses are:

  1. They can be implemented without requiring admin to coordinate with IANA: Using private IP addresses means that network administrators do not have to coordinate with IANA to obtain public IP addresses for use within their private network. This reduces the administrative burden and simplifies network design.

  2. They provide network isolation from the internet: Private IP addresses are not routable over the internet, which means that devices on a private network using private IP addresses cannot be accessed directly from the internet. This provides a level of security by isolating the private network from the public internet.

In addition, private IPv4 addresses can also increase the flexibility of network design, as they can be used to create multiple private networks that do not require access to the public internet. However, private IP addresses are not managed by IANA, as stated in option B, and are not routable over the internet, as stated in option E.
