I kid you not, WordPress.org does not support IPv6 to fetch plugins, themes etc. https://meta.trac.wordpress.org/ticket/3090 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.
