A Minecraft server is a player-owned or business-owned multiplayer game server within the 2011 Mojang video game Minecraft. Players can start their own server either by setting one up on a computer using software provided by Mojang, or by using a hosting provider. Minecraft multiplayer servers are guided by server operators, who have access to server commands such as setting the time of day and teleporting players. Operators can also set up restrictions concerning which usernames or IP addresses are allowed or disallowed to enter the server. Multiplayer servers have a wide range of activities, with some servers having their own unique premises, rules, and customs. Player versus player combat (PvP) can be enabled to allow fighting between players. Many servers have custom plugins that allow actions that are not normally possible in the vanilla form of the game. The largest and most popular server is Hypixel, which has been visited by over 14 million unique players.
