By [Baurtock](https://1up-servers.com/en/blog/author/baurtock/) Updated Oct 26, 2026 · 8 min read Read in[es](https://1up-servers.com/es/blog/servidores-publicos-de-minecraft-java/)[en](https://1up-servers.com/en/blog/public-minecraft-java-server/) **Your game server, free**Ready in 60 seconds, no card.[Create free server](https://1up-servers.com/en/signup/) A public Minecraft Java server is one that anyone can find and join by copying an address, without asking you first. This guide covers what makes a server public, how to open yours without leaving it exposed, how to get it seen, and how to keep order once strangers start arriving. If you have no server yet, start one on our [free Minecraft server hosting](https://1up-servers.com/en/free-minecraft-server-hosting/) and follow our [guide to making a free Minecraft server](https://1up-servers.com/en/blog/how-to-make-a-free-minecraft-server/); the [Minecraft Java server](https://1up-servers.com/en/minecraft-java-edition/) page sums up versions and templates. If you only want a public server to play on, section 1 takes you straight to one. - **Public means four things:** an address that works from outside, **online mode** on, the whitelist off (or a join password) and more slots than your group of friends. - **Being found is a separate step:** nobody sees your server until you list it somewhere. On 1up you switch on **Show on the public list** and your server appears on our public server list with its own profile page. - **Moderation starts on day one:** careful operators, quick bans and the whitelist ready for when a group of griefers turns up. ## 1. If you only want to play on a public server Open our [public server list](https://1up-servers.com/en/servers/). Filter by game, by mode (Survival, Creative, Minigames, PvP, Modpack or Roleplay), by region or by **With room left**, press **Copy IP**, then in Minecraft go to **Multiplayer → Add Server** and paste the address. The list refreshes every 60 seconds and only shows servers that are online right now. If a server carries the **Password protected** badge, open its profile and press **Join with the password**: you type your Minecraft name and the password the owner gave you, and you land on its whitelist. **Invite only** means only players the owner added can join. ## 2. What makes a Minecraft Java server public A server is public when a stranger can join without you doing anything. That comes down to five `server.properties` settings, all described on the [Minecraft Wiki](https://minecraft.wiki/w/Server.properties): | Setting | For a public server | Why | | --- | --- | --- | | Address and port | Reachable from the internet | At home you would forward TCP port 25565 on your router. A host has already done it. | | `online-mode` | `true` | Only players verified with a Minecraft account can join. The wiki warns that with `false`, anyone with a fake account can connect. | | `white-list` | `false`, or a join password | With the whitelist on, players who are not on it cannot connect. | | `max-players` | More slots than your group | The most players online at once. | | `motd` | One line that sells your server | The message shown under the server name in the game's multiplayer list. | **Online mode** is the one setting you never switch off on an open server. Without it the server does not check who you are, so someone can join under your name, and if your name is an operator, with your permissions. ## 3. Open your server on 1up If you are creating the server now, the wizard asks about all of this in its settings step: **Whitelist on**, **Online mode**, **Show in the public list** and **Protect with a password**. For a public server, leave **Online mode** ticked and **Whitelist on** unticked. If you already have a server: 1. In the **Game** tab, **Players** section, check that **Online mode** is on and raise **Max players**. Your plan sets the ceiling. 2. In the **Players** tab, switch **Whitelist on** off if it was on. 3. In the **MOTD** section of **Game**, write the message players see in their server list. The editor has colours and a preview of how it looks in the game. 4. Restart the server to apply the changes that need it. Your address is `yourname.play.1up-servers.com`, with no port, because we publish an SRV record that tells the game which port to use. Nothing to forward on your router. **Shortcut: on 1up it takes three clicks** Your free server in 60 seconds. No card. [Create your free Minecraft Java server](https://1up-servers.com/en/signup/) Be realistic about slots. The Free plan gives 4 slots and 2 GB of RAM, enough to test whether your idea draws people in; Casual gives 6, Starter 10 and Pro 20. Our guide to [how much RAM a Minecraft server needs](https://1up-servers.com/en/blog/how-much-ram-minecraft-server/) helps you tell when you have outgrown a plan. ## 4. Publish your server on the 1up public list A server with a working address is still invisible if nobody knows it. To appear on our list: 1. Open the **Server** tab and, in the **Network** group, the **Address and ports** section. 2. Under **Public list**, switch on **Show on the public list**. 3. Pick the **Mode**: Survival, Creative, Minigames, PvP, Modpack or Roleplay. Players filter by it. 4. Write the **Description**: one line of up to 160 characters, shown on the list and on the profile. Say what sets you apart, not that you are «the best». 5. Press **Publish on the list**. A **View profile** button then appears. The profile lives at `/en/j/yourname/` and shows the address with a copy button, the mode, the description, the version, the region, the players online and how to join from Java, from Bedrock and from a console. It is the link to paste on Discord or social media. Three things to know: - **Only online servers are listed.** Switch yours off and it drops off the list until it is online again. - **The padlock is automatic.** With a join password your server shows as **Password protected**; with the whitelist on and no password, as **Invite only**. - **You can unlist it any time.** Switch the toggle off and your server leaves the list. ## 5. Basic moderation for an open server Opening your server means people you do not know will join. Get ready before the first problem. **Be careful with operators.** In the **Players** tab, the **Operators** list shows who has admin rights. `op` grants level 4 by default, the highest, which includes stopping the server. According to the [/whitelist wiki page](https://minecraft.wiki/w/Commands/whitelist), operators can also always join while the whitelist is on. Only op people you trust. **Kick and ban.** The list of online players has **kick** and **ban** one click away. `ban` puts the account on the server blacklist, stored in `banned-players.json`, and `pardon` removes it, as the [/ban wiki page](https://minecraft.wiki/w/Commands/ban) explains. Our [Minecraft server commands](https://1up-servers.com/en/blog/minecraft-server-commands/) guide has the full syntax. **The whitelist as an emergency brake.** If a wave of griefers arrives, switch on **Whitelist on** in **Players**: from then on only players on it can join. A middle ground is the **Join password**, in the **Server** tab, **Protection** section. Minecraft has no password of its own, so we turn the whitelist on and players who know the password add themselves from the profile page. **Moderators.** From Starter you can invite someone in the **Access** tab with the **Moderator** role. They can kick and ban, but granting or removing op stays with the owner and the co-owner. **Reports.** The public profile has a **Report abuse** link. You run your server and 1up does not moderate its content live, but we enforce our acceptable use policy when someone reports abuse. If you also want phone and Windows Bedrock players, our [Java and Bedrock crossplay with Geyser](https://1up-servers.com/en/blog/minecraft-java-bedrock-crossplay-geyser/) guide explains the bridge. ## 6. How server listing sites work Besides our list, independent websites collect Minecraft servers. Almost all of them work the same way: - **You register and add your address.** The site queries your server with the same status ping the game uses to show the MOTD, the players online and whether it is up. - **They rank by votes.** Players vote once a day and the most voted climb. Many sites hand out in-game rewards to voters through a vote plugin. - **That plugin needs a plugin-capable server.** On 1up, one-click plugins and mods start on Starter; on Free and Casual, create the server with Paper and upload the plugin's `.jar` through **Files**. - **There are paid featured spots.** If you ever pay for one, first check how many people really play on the servers around it. Before you list your server anywhere, have the profile and the moderation ready. ## 7. Get your first players - **A clear niche.** «Vanilla survival for adults, no map resets» draws more people than «fun survival». Use it in the description and the MOTD. - **A community outside the game.** A Discord with rules and announcements keeps people around when the server is empty. - **Consistency.** A server that is off shows on no list. If you are serious, a paid plan keeps it running without depending on your schedule. - **A cared-for world.** Protect the spawn with **Spawn protection** in **Game** and take a backup before every big change; backups start on Casual. If you are torn between starting free and paying, our comparison of [free vs paid game server hosting](https://1up-servers.com/en/blog/free-vs-paid-game-server-hosting/) covers what changes with each plan, and the [pricing page](https://1up-servers.com/en/pricing/) lists the slots and RAM of each. **Shortcut: on 1up it takes three clicks** Your free server in 60 seconds. No card.
