IP Killer 2 is a powerful network stress-testing and denial-of-service (DoS) simulation tool designed for cybersecurity professionals, ethical hackers, and network administrators. It allows users to test the resilience of networks, servers, and firewalls by generating high volumes of traffic to assess their ability to withstand attacks. While it serves as an educational and penetration testing tool, it must be used responsibly and legally, as unauthorized use can lead to severe legal consequences.
