The tool that can do it in 6 minutes is massscan, the original repo of which is the link of the post:

Note that "scan the internet in 6 minutes" only means this tool is capable of generating packets fast enough on the host machine to theoretically do a 6 minute scan. In practice, the NIC, home network, and local ISP connection will bottleneck and the scan will be orders of magnitude slower.
