Are public networks safe against someone finding out the Network ID?

General Discussion

Hey,

I want to use zero-tier to create a private network for my friends and our Minecraft server. I have succeeded but for convenience I would like to keep the network “Public”. Unfortunately, the server which is running the VPN is also containing some personally sensitive data and is running on a privileged container, and I’ll be honest, I’m not confident it’s resistent against attack if the VPN would be comprimised.

I am wondering if the Network ID is safe against being guessed or found out? It’s quite a lot of entropy, assuming all 16 characters are random, so it should be hard to guess it. For the sake of discussion, let’s assume all my friends are 100% trustworthy, I am more concered about insecurities in the protocol / implementation.

Thanks for any advice!

Public networks are just that. Public. Anyone that knows the ID can join and will be automatically authorized to access the network.
