How to Make a Minecraft Server for Your School or College Friends (Free)

Play Minecraft with classmates and hostel friends for free: host from home or your laptop, share one address, keep strangers out with a whitelist, and what to do when campus Wi-Fi blocks you.

Realms costs money every month, and “Open to LAN” stops working as soon as someone goes home. If you want one Minecraft world for your class, batch or hostel, the cheapest way is to host it yourself and share an address. It takes about five minutes and costs nothing.

Who should host

The world lives on the host’s PC, so it’s only online while that PC is on. Pick the person who:

Want two hosts? Take turns: zip the server folder, share it, and the other person uses Import Existing Server. Only run it on one PC at a time, or the world splits into two copies.

Set up the server

Get VoxelPort from the Microsoft Store (Windows 10 and 11), download the Windows installer directly (if Windows warns, click More info → Run anyway), or get the Linux build from GitHub. It's free, open source, and needs no account.

  1. Click + Add Server and pick Survival SMP. If some friends play on phones, pick Java + Bedrock instead.
  2. Give it 3–4 GB of RAM, agree to the Minecraft EULA, and click Install & start.
  3. When it says Online, click Make public.
  4. Supporters can claim a name such as ourclass.voxelport.in under Get a custom address; the free address also stays the same between restarts.
  5. Post the address in your class or hostel group chat. Friends add it under Multiplayer → Add Server.

Keep strangers out: the whitelist

Anyone who sees a public address can try to join. If the server is only for your group, turn on the whitelist:

  1. In VoxelPort, open the server’s Settings and turn on white-list.
  2. In the console, add each friend by their Minecraft name: whitelist add Name.
  3. Make yourself an operator with op YourName so you can manage the game from inside Minecraft.

Players who aren’t on the list see “You are not whitelisted on this server” and can’t join.

Campus and hostel Wi-Fi problems

ProblemWhyWhat to do
Friends in the same hostel can’t see your LAN worldCampus Wi-Fi isolates devices from each otherUse the public address instead of LAN
A friend on campus Wi-Fi gets “Connection timed out”The network blocks game portsThat friend joins from mobile data or a hotspot
The host can’t go public from campusThe network blocks the connection to the relayHost from home, or from a phone hotspot (watch the data)
Campus networks have rules. Don’t try to get around blocks your college has put in place on purpose; host from home instead.

Ideas for a class server

Questions

Can I host a Minecraft server on college Wi-Fi?

Often yes, because VoxelPort only makes an outgoing connection, like a website. Some campus networks block games or unusual ports. If it doesn’t work, host from home or use a mobile hotspot, and follow your college’s network rules.

Why can’t my friends in the same hostel see my LAN world?

Many hostel and campus networks use “client isolation”, which stops devices on the Wi-Fi from talking to each other. LAN worlds can’t be seen there. Putting the server online with an address gets around it.

How many friends can join a free server?

It depends on your PC and upload speed, not on VoxelPort. A normal laptop giving the server 4 GB handles about 5–10 players on Paper; a desktop handles more.

Do my friends need to pay or sign up?

No. They need their own copy of Minecraft. Nobody needs a VoxelPort account, and only the host installs VoxelPort.
