Angry IP scanner is a great little tool I’ve used over the years to get a quick view of what is on a network I have limited knowledge of. Angry IP Scanner is widely used by network administrators, IT professionals, and security experts for tasks like network diagnostics, device discovery, and security audits. Its user-friendly interface makes it accessible to both beginners and experienced users
