I recently tried to deploy GitLab from scratch on an IPv6-only network, and the initial experience was anything but smooth. I was met with an exception right in the console during the initial setup. GitLab attempted to obtain a Let's Encrypt certificate and immediately failed, as it doesn't listen to IPv6 addresses by default. A year ago, we (at work) faced similar issues when trying to deploy GlusterFS on an IPv6-only network, and it also failed. (I pushed for V6 only, my manager was not happy) It's evident that while IPv6 may be the future, the present ecosystem doesn't seem fully prepared to support it. For years, I have wanted to use Docker with IPv6 only, and I am really thinking about learning Go so I can write my own IPv6-only driver.
