Yup, my family minecraft server fell victim to that. Thankfully it was a new map with only a couple days' work into it, but annoying nonetheless. Whitelist your private servers!
Requiring a VPN is how I handled that - not so much for preventing people from joining the game but because I don’t like open ports. I’m surprised that VPN usage isn’t more common for minecraft players.
I’m kind of amazed that you can still do massive scans like this and not face some bad consequences like getting blocked somewhere, or having your hosting provider get very annoyed at you.
Your host isn't likely to care unless it causes them grief. There are so many scans happening at any given moment I doubt any of the targets will notice yours. I do vaguely remember one of these, "I scanned the whole internet! It's easy!" stories from years ago where the author wound up receiving an email from someone at Electric Boat who told them, "Please don't portscan us. We're required to call the FBI when it ha…
Our Minecraft server is spun up only when we play, with a simple bespoke front-end that allows any Cognito-authenticated user to start or stop the AWS instance. The dashboard also shows an auto-updated leaderboard with some in-game stats (death count, miles traveled, last login and so on), stored in DynamoDB and periodically updated by a cron job on the server. I also planned to add a map of the spawn, but not sure i…
I'd love to read a blog post or a link to a repo to see how this is done. Sounds very fun and interesting!

I've got a similar setup myself, check out https://lobste.rs/s/yppnts/tailscale_on_nixos_new_minecraft_... where I describe how I did it. It's quite custom but all open source. https://github.com/infinisil/on-demand-minecraft is the main part
Part of my idea was an actual web home for the server (leaderboard, map, etc.) so if we play MC again I will see if that is possible with your project.
I... kinda can't believe that one of my libraries (Forgelin) is the second most common mod on all Minecraft servers. It doesn't support the five most recent versions of the game and I haven't touched it in years. I guess there are a lot of other mods (or a few really popular ones) for somewhat older versions that use Kotlin.
One thing the author may have missed here because I didn’t see it mentioned: this also misses any servers not hosted on the default port of 25565. I don’t know how common this really is, but Minecraft has SRV record support, and for those of us running more than one Minecraft server on a single box it’s likely at least one will be on a different port.

1 packet going out to 4 billion hosts probably doesn't even matter next to a few 4K video streams. I expect if author had launched it through CGNAT, someone wouldn't have been pleased. (Correct me if I'm wrong)

So a proper census would do a reverse dns lookup on every IP looking for a "minecraft" SRV record and connecting to that.
