What is a Dedicated Game Server? (And Why You Need One)

If you've ever tried to play a multiplayer game with friends and wondered why one person's internet connection affects everyone else's performance — or why the server goes down when the host closes their game — you've already experienced the problem that dedicated game servers solve.

This guide explains what a dedicated game server is, how it works, how it compares to alternatives like peer-to-peer and listen servers, and how you can get one completely free.

What is a dedicated game server?

A dedicated game server is a computer (or a virtual machine running on a computer) whose sole purpose is to host a multiplayer game. It runs continuously in the background, managing the game world, processing player actions, and keeping all connected players in sync — without any player needing to have their game client open.

The word "dedicated" is the key. Unlike a setup where one player hosts the game from their own PC while also playing, a dedicated server is dedicated entirely to the task of hosting. No one is gaming on it. No one needs to be home. It just runs, constantly, doing its job.

How does a dedicated server work?

When you connect to a dedicated game server, here's what happens behind the scenes:

1. Your game client connects to the server's IP address over the internet, just like a browser connects to a website.
2. The server authenticates you — checking your username, any password, and whether you're whitelisted if applicable.
3. The server sends you the world state — what the current game world looks like, where all entities and players are, and what's happening in real time.
4. You send actions to the server — when you move, build, attack, or do anything, your game client sends that action to the server rather than applying it directly.
5. The server processes and broadcasts — the server validates your action, applies it to the authoritative game world, and sends the update to all connected players simultaneously.

This central authority model is what keeps everyone in sync. The server is the single source of truth for the game world. No single player can have a different version of reality.

Dedicated server vs listen server vs peer-to-peer

There are three main ways to run a multiplayer game. Understanding the difference explains why dedicated servers are so much better for a consistent experience.

Peer-to-peer (P2P)

In a peer-to-peer setup, players connect directly to each other with no central server. Each player's game communicates with every other player's game simultaneously. This works for very small groups but creates problems as player count grows: everyone needs to send data to everyone else, and one player with a slow connection drags the experience down for everyone. Most modern games have moved away from pure P2P.

Listen server

A listen server runs on one player's gaming PC while they're actively playing. That player is both a client (playing the game) and a server (hosting it for everyone else). This is what happens when you "host a game" in many titles. The problems: the game runs worse on the host's machine because it's doing double duty; everyone else's latency depends entirely on the host's internet upload speed; and the server shuts down the moment the host player quits. There's no persistence.

Dedicated server

A dedicated server runs on separate hardware with no game client. All of its CPU, RAM, and bandwidth is devoted entirely to serving the game. Players connect to it regardless of what the host is doing. The server stays online 24/7 whether or not anyone is playing. Performance is consistent and independent of any player's hardware.

Why you need a dedicated server

Whether you're running a Minecraft world for your friend group or a Terraria playthrough with three players, a dedicated server solves problems you might not even realise you have yet:

Your friends can join without you

With a listen server, the game shuts down when you close it. A dedicated server runs around the clock, so a friend in a different time zone can hop on while you're asleep. Your world keeps growing, events keep ticking, and everyone picks up where they left off.

No one gets lag from the host's connection

When one player hosts from their PC, every other player's ping is determined by that host's internet upload speed. If the host has a slow or unstable connection, everyone suffers. A dedicated server sits in a data centre with a high-speed, low-latency connection that's far better than any home broadband.

Better performance overall

On a listen server, the host's PC is running the game client and the server simultaneously. This splits resources and leads to lower frame rates, stuttering, and server-side lag. A dedicated server runs only the game logic, with no graphical overhead, making much better use of its hardware.

Full admin control

Dedicated servers give you access to a full server console where you can kick, ban, whitelist, and OP players; change game rules; run commands; view logs; and manage your world — all without being in-game. This is essential for running any kind of community server.

Your world is always safe

Dedicated server hosts like FreeGameHost run automatic daily backups, meaning your game world is protected even if something goes wrong. With a listen server, your world files live on someone's personal PC — one hard drive failure away from being gone forever.

What does a dedicated server need to run?

If you're curious about the technical requirements, here's what goes into running a game server:

• RAM — The most important resource. Minecraft needs 1–2GB minimum for a vanilla server, 4–8GB for modded. Most games have published minimum RAM requirements for their server software.
• CPU — Game servers are mostly single-threaded, meaning a single fast CPU core matters more than many slow ones. Hosting providers express this as a CPU percentage allocation (e.g. 200% = two full cores).
• Storage — Game worlds grow over time. Minecraft worlds can reach several GB after heavy exploration. NVMe SSD storage is preferred for fast chunk loading and low read/write latency.
• Bandwidth — Each connected player sends and receives data constantly. Most games use 50–200KB/s per player. A 10-player server needs roughly 1–2MB/s of sustained bandwidth.
• A static IP or domain — Players need a consistent address to connect to. Hosting providers give you a permanent subdomain (like yourserver.freegamehost.xyz) that never changes.
• DDoS protection — Game servers are frequent targets for DDoS attacks, especially if you share your address publicly. A good host includes DDoS mitigation as standard.
