Some hosting providers like scaleway allows to remove the IPv4 from the VPS in order to save 1€/month but doing this will result in losing connectivity to the "IPv4 world".
Or you may have ordered a VPS that only has IPv6 connectivity and you want to access to a resource only accessible from the "IPv4 world".
Here is how to gain your access back to the "IPv4 world".

Change your name servers(s) to DNS64 name servers(s)

Note: You may deploy your own DNS64 & NAT64 server on a separate server by following this tutorial (untested): https://packetpushers.net/nat64-setup-using-tayga/.
Note²: You may find a explanation of what is NAT64 and DNS64 on Wikipedia.

Choose a/multiple DNS64 public server(s) that has/have its own NAT64 public service from this list:

How to use this gist

You've got two main options:

Why did you do this?

Relax, I only have one Sunday to work on idea, literally my weekend project. So I tried Deepseek to see if it can help. Surprisingly, it works and it saves me another weekend...

What is your setup?

Just chat.deepseek.com (cost = free) with prompts adapted from this gist.

Does it work in one-shot or I have to prompt it multiple times?

Add the RPMFusion repositories (both free and non-free) to the YUM repository directory (/etc/yum.repos.d/):

sudo dnf localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

Install the patched version of FreeType with subpixel rendering enabled:

sudo dnf install -y freetype-freeworld

	package main

	// This is how you can manually initialize a window and OpenGL context on windows, instead of using SDL or GLFW.
	// Also renders a colorful quad onto the screen.
	// I made this as an exercise and getting into Odin.
	// This is my first "complete" odin program, so there's probably much better ways of doing this :D
