Normally, Mario Kart in Minecraft is hosted on neogamesmc.net. Well, because that server has been down for the past few months, and I have no clue when it is coming back again, I am hosting this server here:
(This may possibly slightly change. If you find that the server is offline, it will for sure. This is because it is hosting a LAN server to the public. I do it this way because for some reason my PC won't run a server and the actual game at the same time and work properly.)
As long as I don't accidentally close it down again, it will be active as much as I can allow it to be (If I am in my school, and since I am homeschooled, I have to shut it down, meaning the IP address will slightly change).
This world will be shut down once the neogamesmc server is online again.
