In an hping3 command, which option is used to spoof the source IP address?

• A. -a
• B. -S
• C. -p
• D. -I

Answer: (A)

Setting a spoofed source IP address in hping3 is done with the -a flag. This option overrides the source IP field of the packets you craft, allowing you to specify any IP address you want as the origin. It’s useful for testing how a target or network defenses react to traffic that appears to come from a different address, or to simulate scenarios where replies would go to the spoofed address. The other options influence different parts of the packet: one toggles the TCP SYN flag, another sets the destination port, and another selects which network interface to send from. Since those don’t change the source IP, they don’t achieve spoofing.
