Minecraft Server
What is Port 25565?
Port 25565 is the default port for Minecraft Java Edition game servers, one of the best-selling video games in history with over 300 million copies sold. Minecraft servers allow multiplayer gameplay where players can build, explore, and survive together in generated worlds. The Minecraft server software listens on port 25565 for client connections, handling game state, player interactions, and world persistence. Both the official Mojang server software and popular alternatives like Paper, Spigot, and Fabric use this port. Minecraft servers range from small private servers for friends to massive commercial networks like Hypixel hosting tens of thousands of concurrent players. The Minecraft modding community has built extensive plugins and modifications that extend server functionality.

Security Considerations
Minecraft servers can be targets for DDoS attacks, griefing, and exploitation. Use whitelist mode for private servers. Install anti-cheat plugins. Keep server software updated to patch vulnerabilities. Use a DDoS-protected hosting provider for public servers. Don't run Minecraft servers on the same machine as critical services. Consider BungeeCord/Velocity for network-level protection.
