How to Find My "Minecraft" Server's IP Address

Multiplayer games in "Minecraft" require the player hosting the game to share their server's IP address with the other players. Without this address, other players can't tell their "Minecraft" client what server to connect to, and therefore can't join the game. There are two ways to get your IP address, each suited to a different type of game. For play over a local area network, where all player computers are connected on the same network, you'll need the host computer's device IP address. For games played over the Internet with friends outside the network, you'll need your network's external IP address.
Log on to the server's host computer and press "Windows-X" to launch the power user menu. If you're using a different computer to host the server than you will be to play, you need to perform these steps on the host computer. The IP address of the computer you'll be playing on won't be useful for this process.
Select "Command Prompt" from the power user menu and enter the "ipconfig" command when it loads. It may take a moment for your computer to load all the IP information, including the address you need.
Make a note of the "IPv4 Address," which is your computer's local IP address. This is the number you'll need to give out to the other players, as well as the IP address you'll need to connect to if you're going to play on a computer other than the host computer.
Start up your "Minecraft" server software and bring the server online. Once the server is up and running, you need to get in contact with the other players and give them the IP address so that the game can begin.
Over the Internet
Log on to the server's host computer, and open your preferred Web browser. The command prompt's "ipconfig" command isn't useful for games played over the Internet, as the device IP address for your computer is for internal use by devices and services within your local network.
Connect to an IP discovery website like "What Is My IP," "What Is My IP Address" or "What's My IP address" (links in the Resources section). These sites can inform you of your computer's external IP address. This address is the one you'll need to distribute to the other players.
Start up your "Minecraft" server software and bring the server online. Without an online server, there isn't anything for your fellow players to connect with, and therefore no game.
If you're playing on the computer that is also hosting the server, only the other players need the IP address. When entering the address, using "localhost" will connect you to the server in the same manner as the actual IP address would.
Playing "Minecraft" on the computer hosting the server is generally not advisable, unless you have a fairly powerful computer. Running the server and the game at the same time draws a lot of your system resources, slowing down any other processes and generally producing a laggy experience.
Unless you've secured a static IP from your Internet provider, your external IP address will change periodically. Check your IP address before each multiplayer session to make sure that your friends will actually be connecting to your "Minecraft" server.
Don't give out your server's IP address to players you don't know or trust. Multiplayer with new people is fun, but people you aren't familiar with could potentially grief or troll your server. Get to know people a bit more on other servers before you invite them to your own.
