What type of spoofing attack uses fake source IP addresses that are different than their real IP addresses?

MAC spoofing involves changing a device's Media Access Control (MAC) address to impersonate another device on a local network, not its IP address.

IP spoofing involves an attacker crafting network packets with a fabricated source IP address to conceal their identity or impersonate a legitimate system. This technique is often used in denial-of-service attacks, to bypass network access controls, or to facilitate other forms of deception.

Application spoofing is a broad term that refers to impersonating an application or service, but it does not specifically describe using fake source IP addresses in network packets.

Name spoofing typically refers to impersonating a person or entity by faking their name, often in phishing attacks, and is not directly related to altering IP addresses in network packets.
