I attempted to join my brothers local mc server I have the IPv4 Address and the numbers but it always says can't connect to server It works in our house but in our other house it doesn't work. We are using mods if that affects anything (We used mods before and it worked perfectly)

We're at a different house than what we're normally at to play together.

    The IP address that you use at your house vs. the one at this new house are probably different. Double check to make sure you've got the right one. – Mage Xy May 17 '17 at 19:54

To avoid too much techno-babble, I'll try and keep it as simple as I can.

Basically, an IP address is the same as a Street Address. More often than not, when you connect to a different network, your IP Address will change. How the server reacts to that, depends on the setup. It sounds like they have allowed a specific address, but whether that is an internal or external address is also applicable. (An internal IP is the address of your Laptop/PC within the local network, and an external IP is the address of your whole network, that is exposed to the internet.

You can identify what your IP is easily by following these steps:

  • For an internal IP:

    1. Open a "Command Prompt" by right-clicking on the start menu, and choosing it from the pop-up menu, or by searching for it by typing "cmd" into the search.
    2. Once open, type "ipconfig", then press enter. A whole lot of info will appear, but you are looking for a line that says: IPv4 Address...... This will show you your laptop's internal IP.

  • For an external IP:

    1. Open your internet browser, and go to google, then type in "What's my IP". This should bring up a response with your external IP, which is the IP for your external network. Now, in the case of being on the same network as the server, this will be less useful, but if you are on separate networks, any device with that external IP will be allowed on the server, regardless of the internal IP.

Adding these IPs to the server list will then allow you to connect.

    The internal IP method only works on Windows. To find your internal IP on a Linux machine (maybe also Mac?), open the terminal and run ifconfig | grep -w inet. Look for the number which starts with 192.168. –  May 18 '17 at 00:28

you have a different IP in the other house than the one at your house. Everything its going to be different so you will need to find out the IP at the new house. Depending on the device you are using, you can look at the network options in the settings.

  • Hey John, while this answer is a good start, you might want to give some more context on how the OP might discover the different IP addresses between houses. – nightsurfer May 17 '17 at 20:28
