Do not disclose private IP addresses and routing information to unauthorized parties.

Do not disclose private IP addresses and routing information to unauthorized parties.

• A. Do disclose private IP addresses to vendors.
• B. Publish private routing information in public forums.
• C. Do not disclose private IP addresses and routing information to unauthorized parties.
• D. Use public IP addresses internally.

Answer: (C)

Protecting network topology and routing details is essential because these specifics reveal how systems are connected, where sensitive assets sit, and how traffic flows through the environment. If private IP addresses or routing information fall into the wrong hands, an attacker gains valuable reconnaissance data, which can be used to map the network, identify targets, and plan precise exploits. That kind of information should be accessible only to authorized personnel on a strict need-to-know basis. When a vendor or any external party truly needs access, it should be granted through secure, controlled channels and limited to the minimum information necessary, with appropriate access controls and monitoring. Using secure remote access and network segmentation helps keep internal addresses protected while still enabling legitimate work. Publishing private routing details or exposing internal addresses publicly would dramatically increase the risk, and using public addresses internally would undermine the purpose of private addressing. Therefore, the best practice is to avoid disclosing private IP addresses and routing information to unauthorized parties.
