where can i find my server's ip?

This option starts a server on your computer, so the IP is "localhost", but only you and the other computers on the same Wifi can access to this server.

The server starts in offline mode. Which means it will not allow outside connections unless the online-mode value in the server.properties file is changed to true. I don't know where the server.properties file is located or if it is even editable in this form. If you want to connect while on the same network as the host machine. You simply put the local ip address of the host computer along with the port (52463) in this format into the server address box on your client pc that you want to join the server with.

[Your Host computer local ip here]:25463 most likely, it would be something like 192.168.1.12:25463. You can find this ip by typing ipconfig into the cmd and looking for the IPv4 address value.

If you're wanting to just test a mod with your friend, I would say just export the the mod and then upload it to a locally hosted server on your computer. All you have to do from that point is just give them a copy, set up port forwarding with your router, then turn on the server. The server ip would be [Public ip of host machine]:[Port] The port is usually default 25565.

In order to get a local server client. go to the forge website and download the version you want then just click install server in stead of install client. I suggest making a batch script to start the server so you can give an allotted amount of RAM to use. You can search how to do that on google.

Hi tsmufo, I hope its not late ,I have the same issue and this steps could help me :
If you have already installed Minecraft, you don’t need to install Java. But if you don’t, download and install Java.

1. You should create a folder on your computer to store all Minecraft files. As running a server needs so many files, it is much easier to keep all of them just in one place.
2. You must Right-click the .jar file and select the Run as administrator option.
3. Now open the eula.txt in the application folder and change the false value to true (eula=true)
4. As we explained earlier in this article, open Command Prompt and navigate your Minecraft folder.
5. Now write ‘java -jar minecraft_server.1.9.5.jar’ and click on Enter. Changing the filename to whatever your Minecraft jar file is called would be best.
6. At this point, you have to check to see whether your Minecraft server is visible or not. Use your server IP address and select check.
7. To play on your server, you should type Localhost. Based on what you have set up, your guests must put your server name or IP address to play.
