You have created the server so that only you can access it. The whole point you decided to make a Minecraft server was so that you and other people could play Minecraft on the same world and interact with each other. It would be boring for you to play all alone so I will show the steps to allow others to join your Minecraft server.

1. First, open CMD by pressing Windows key + R and then typing "cmd"

2. Now that CMD is open, you can type "ipconfig", hit enter, and then close it. You should see a screen with lots of numbers and letters. This is the information about your internet connection.

3. Go down to Default Gateway and copy the the number. It should be something along the lines of 192.168.0.1

4. Open the web browser you prefer and copy the number into the URL address field.

5. Log into your internet router.

6. Click on the advanced settings button to access the section port forwarding. Click on "Add New" and enter "25565” as the port number

7. Open CMD again by pressing Windows key + R and entering "cmd". Find your IPv4 Address and use that address as your IP address.

8. Next, you will need to find your public IP address by clicking here

9. To allow people to join your servers, you need to give them the public address followed by "?25565". games It should look something like "PublicIP:25565".

Now you and your friends can play together in the same Minecraft world. The IP address is probably not what you were hoping to give people but to have a IP address like "us.mineplex.com" but to do that it costs money and is much more complicated.
