I literally just had one of my university friends ask me about IPv6 today.

I've got IPv6 running at home: https://battlepenguin.com/tech/setting-up-ipv6-on-a-linux-router/

and in my Docker environment: https://battlepenguin.com/tech/docker-with-ipv6-and-network-isolation/

...but yea it's frustrating and a mess to setup. Once it's running I can pretty much leave it untouched though.
