Which flag enables IPv6 scanning, and what is a correct example of its usage?

• A. -4 enables IPv6 scanning; Example: nmap -4 2001:db8::1.
• B. -8 enables IPv6 scanning; Example: nmap -8 2001:db8::1.
• C. -6 enables IPv6 scanning; Example: nmap -6 2001:db8::1.
• D. -6 enables IPv4 scanning; Example: nmap -6 192.0.2.1.

Answer: (C)

The flag that makes Nmap use IPv6 for targets is -6. By forcing the address family to IPv6, Nmap will connect to and scan IPv6 addresses rather than IPv4 ones. The example nmap -6 2001:db8::1 correctly uses an IPv6 literal as the target, demonstrating how to apply the flag in practice. The other options aren’t correct because -4 specifically forces IPv4, not IPv6; there is no standard -8 option in Nmap for IPv6; and saying -6 enables IPv4 scanning conflicts with what -6 does, as shown by the IPv4 example.
