Correct Answer: CD

Reverse lookups, also known as reverse DNS (Domain Name System) lookups, can be used to verify the authenticity of the source IP address of a network connection. This helps prevent Internet protocol (IP) spoofing, where an attacker tries to impersonate a legitimate IP address to gain unauthorized access or carry out malicious activities. By performing a reverse lookup, one can check whether the hostname associated with an IP address matches the expected hostname, thus helping to detect and prevent IP spoofing attempts.
