how to host server with my own PC?

I wonder know why this server can host 1000 slots and it is not from server provider
net.connect 220.133.151.99:28015

You cant yet. You have to rent a rust server from a GSPS.

so… what happen to those server like this one?
I doubt they rent server

I don’t think the game even supports 1k. It might be copied server files which were modified.

it does, I mean that server does

1000 slots on a home PC
