This is a directory of more than 5,000 Minecraft servers that I have found using a port scanner, featured in my video. Note that it is a proof of concept and I had only scanned a few IP ranges, to not exhaust rate limits and avoid legal issues. If you want to scan your own IP ranges, please download the project from github.com/numenmc/mc-scanner. If you do scan 0.0.0.0/0 and want to share the data, contact me over at my discord server and I might add it here.
You can also download the raw data: /api.json
If your server is listed here, please ensure you have a whitelist or backups for your server. You can also contact me to remove it from the list.
