Hypixel.net is both their website and mc server adress.
Is it just that https is on port 443 and minecraft is on port 25565?
And if that is the case, can i do something similar by making a reverse proxy have two seperate server blocks for the one domain, with different ports?
Oops you are right.
A quick search said mc uses tcp
Most games use UDP as the latency induced by TCP is unacceptable for games
Minecraft java, for some reason, doesnt
Minecraft is a building game where latency does not matter as much as in shooter games. For example, if your latency is 200 ms, you can play Minecraft smoothly, while in FPS games it is unacceptable 😉
Edit: In addition, the Minecraft server can use UDP protocol to serve the server status (but only for this purpose and it is not, nor has it ever been used by the game client). In the past, it was used to display the number of players on websites with server listings, but this can be considered deprecated now – today they use the same protocol as the game client.
