IPv6 support

[Guillaume]

As stated here: https://letsencrypt.org/docs/ipv6-support/, let's encrypt now supports IPv6 and prefers it over IPv4. It would be great if this addon didn't absolutely require an IPv4 address to work.

For example given a balancing node which already has an IPv6 address attached, do not create an IPv4 address, otherwise do it.

Hello, is there any news on this ?

Hello, @ovesco.
Thanks for your patience.
Actually, the issue was fixed a couple of months ago under another task: 6ae8083.
You can try to attach IPv6 to the balancing node and install the add-on after that.
