Question about "proper" way to run v6/v4 website

[Tim]

Hello,

Thanks everyone for the feedback on this.  Some of your explanations
were clear enough for me and my limited understanding to comprehend.
I've learned of enough reasons not to do what I proposed, so I'll go
back to simply providing separate subdomains.

On the topic of AAAA glue records, does anyone know if .us has plans on
supporting them anytime soon?

cheers,
tim
