Scanrand
This is a scanning tool that has been specifically made to be extremely quick but effective. It tops most other scanning tools with its fast speeds, which it achieves in two ways. The tool contains a process that sends multiple queries at once and another process that receives the responses and integrates them. The two processes do not consult and therefore the receiving process never knows what to expect—just that there will be response packets. There is, however, a clever hash-based way that is integrated into the tool that allows you to see the valid responses that it receives from scanning. The tool is totally different from old scanning tools such as NMap, and its advancements enable it to be quicker and more effective at capturing packets.
