Of course they are.

I’ve tried multiple times to go IP6 only. I mostly thought, despite my reasonable understanding of IP4, that I was the problem in trying to set it up. I found my dns host was being forgotten multiple times a day, set to something invalid, then it would time out and revert back to the working one. I couldn’t figure out how to connect two computers together for Minecraft.

Now I hear it was just garbage consumer hardware and software? Fuck me. So much wasted time and effort to say nothing of believing I had turned into a tech idiot.
