What is a private IP address, and when would you use this?

How to Answer
Answer Example

As the Cisco network engineer interview progresses, the questions will become more complex and in-depth. This indicates that the interviewer is gaining confidence in your capabilities and is willing to explore your knowledge in more detail. Regardless of the complexity of the technical or operational questions you are asked, continue to keep your answers succinct. The Cisco interviewer will ask follow-up questions if they need more information or if the topic is critical to the organization's operations.

"Private IP addresses are used to identify user nodes on internal networks, also known as intranets. These maintain the anonymity of the users to anyone outside of Cisco. When users need to transmit data across the Internet, their addresses are translated into public IP addresses using NAT protocols. I use private IP addresses to keep internal user addresses secure. I also sometimes use them when I need to duplicate IP addresses on separate networks which do not see each other except when connected over the Internet."
