IP pullers are software tools that can extract or "pull" the IP addresses of devices connected to a network, in this case, Xbox consoles. These tools leverage various methods, including packet sniffing and exploiting vulnerabilities in network protocols, to gather IP addresses. For Xbox gamers, knowing the IP address of another player can be used for various purposes, ranging from improving online gaming performance by reducing latency through direct connections, to more malicious activities such as DDoS attacks.
