A friend of my lately introduced to tools called advanced IP scanner. It a great tool. It basically scans all addresses to check the address of device even if this device is not in our network. When I connect a device on my computer and I don't know its IP address. If the device has 1.1.1.1 or 3.3.3 or 6.6.6.6 8.8.8.8 this tool will find it. A tool like Nmap works to find it if I know the range where my device could be.
I was wondering if there is a Linux alternative for this tool.
