The IP address (Internet Protocol) is a series of numeric values, used to connect to your server by other players. An IP address is assigned by your ISP, and it could be “Dynamic” or “Static”. Dynamic IPs change after each reset, while “Static” IPs remain unchanged. Static IPs are the preferred option, since players will not have to change the login IP each time you reset your router’s connection.

Offline Servers

Offline Servers are often referred to as cracked ones, meaning players with pirated versions of Minecraft can join them.

If the Mojang API is not working, many Online mode servers will not work until the API is running.
