@alexhaydock heh, I remember trying this and just quitting when it didn't work. It was the first approach I had in my head to access IPv4-only sites from an IPv6-only connection. Thanks for documenting this, I'll be sure to try this out when I look at this again.
My home networks have had IPv6 for over 20 years (more than half my life), luckily always through my ISP. Great to see your posts!!
