Why is it important to protect or hide IP addresses from hackers?

1. IP addresses use only private protocols

2. IP addresses uniquely identify a device on the network or internet

3. IP addresses have no significance in networking

4. IP addresses are temporary and change frequently

The correct answer is: IP addresses uniquely identify a device on the network or internet

Protecting or hiding IP addresses from hackers is important primarily because IP addresses uniquely identify a device on the network or the internet. This unique identification allows other devices on the same network or the broader internet to communicate directly with that specific device. If an attacker knows an IP address, they can target that specific device for various forms of cyber attacks, including denial-of-service (DoS) attacks, exploitation of vulnerabilities, or unauthorized access. By obscuring or protecting IP addresses, organizations can significantly reduce their risk exposure. It helps prevent attackers from easily identifying potential targets. Additionally, it adds a layer of anonymity and security, making it more challenging for malicious parties to carry out their plans. In contrast, the other options highlight aspects that do not accurately represent the significance of IP addresses in the context of cyber threats. For instance, IP addresses do not solely use private protocols, nor are they insignificant in networking; they play a crucial role in how devices communicate. While some IP addresses may change frequently due to dynamic allocation, the practice of protecting them remains important regardless of their volatility.
