I kid you not, WordPress.org does not support IPv6 to fetch plugins, themes etc.

https://meta.trac.wordpress.org/ticket/3090

"The WordPress.org systems team DO have IPv6 plans, but at present there are higher priority tasks and there's no widespread requirement for IPv6 connectivity."

Its not possible to run a WordPress instance and auto-update with IPv6-only and without any kind of adress translation.

Ticket is 6 years old by the way ...

Wordpress auto-update is fundamentally broken, anyway, which is why it's still one of the most popular phishing site hosting platforms out there.

This is sad, but not surprising.
