Are you wondering why many people use a dedicated IP Minecraft? Check it out!
A minecraft dedicated IP means that you will be able to access minecraft on the standard port 25565 on your minecraft server (thus removing the need of putting in an additional port when connecting). In most instances, a dedicated IP address is recommended as you will run into less problems configuring the server and you will also have a unique IP which nobody else is aware of.
What this means is that you can use the default Minecraft port of 25565, which is optional to enter to join a server.
So you only have to enter in the IP without the trailing :port number. If you have a URL redirect, it also means you won’t have to append the port after the URL to join your server. This allows your server to appear more professional and is easier to memorize and join.
