I am building a Minecraft server and the computer running it has a generic 192.168 IP. Do I need to change it when I am putting into Google Domains (so it does not confuse it with another one)? If so, how do I change my IP address so the Google Domains, and sequentially, Minecraft, does not confuse this with another IP. Is this even how it works? Thanks!
Your 192.168 IP address is an address assigned on your local network. It is so that computers connected to your local network can find each other. If you are connected to the Internet, you will also have a public IP address. You can check that by typing what is my IP address in Google search. This address is used by computers on the Internet to find your local network. Unless you have a static IP address from your Internet Service Provider, your public IP address will change from time to time. Having a static IP address means that your public IP will not change and therefore you can direct users to that IP address, or attach a domain name to the IP address in your DNS records to make it easier for users to remember. You'll also need firewall rules amended on your router to allow traffic in to your private network through whatever port is used by your Minecraft server.
