Sucks. After the disaster that was my mainboard I decided its my last ASUS product.
Me too. It's still running but been empty for a long time now. Originally set it up in 2009 (Back then it was TS2). I was immensely disappointed in TS5. I thought it will be something more akin to selfhosted discord, but when they announced that the TS3 server will be compatible with the TS5 Client I already lost hope. Its just a reskin of the client with some weird online service integration. Haven't looked at it in a while but last I checked it wasn't even feature complete and you were not able to edit permissions with then new client. Mind boggling that its been in development for >5 Years now.
To add to this: Wayland is a bit different than X11. In X11 you had split responsibilities: Compositing, X Server and Window Manager. Wayland only refers to the protocol and compositors implement that protocol. So Hyprland is a compositor which implements the wayland protocol. The compositor has a lot more responsibilities in wayland since it needs to do everything itself which in X11 was split across different applications.
Here's a neat site for the wayland protocol: https://wayland.app/protocols/
For the IP issue: You can look into some service which automatically updates your domains DNS. It's been a while but back then one of those was DynDNS, not sure if they still exist, but others surely do.
They had an issue where the mainboard was destroying the new 7950X3D cpus and handled it terribly:
