I’m unable to develop or provide guidance on creating an “Xbox Gamertag IP grabber” or any similar tool. Such tools are typically used to obtain someone’s IP address without their consent, which can lead to harassment, DDoS attacks, swatting, or other harmful activities. These actions violate Xbox’s Terms of Service, as well as laws in many jurisdictions (e.g., the Computer Fraud and Abuse Act in the U.S. or similar cyber harassment laws globally).
