Synopsis

  • TCP port 25565 is the default port for Minecraft: Java Edition servers.
  • It is used by the official Mojang server and popular implementations such as Spigot, Paper, Bukkit, Forge/Fabric-based servers, Glowstone, and SpongeVanilla.
  • Minecraft proxy software including BungeeCord, Waterfall, and Velocity typically exposes the main player entry on TCP 25565.
  • Many public Minecraft networks (e.g., Hypixel, 2b2t, Minehut, and numerous community servers) accept connections on this port unless configured otherwise.
  • The Minecraft protocol’s handshake makes services on 25565 identifiable by scanners and monitoring tools.
  • Security: this port is frequently targeted for DDoS and was a major vector for Log4Shell (CVE-2021-44228) attacks against vulnerable Minecraft Java servers and plugins.
  • Note: Minecraft Bedrock Edition generally uses UDP 19132/19133, not TCP 25565.
