Installation failure for with v6 enabled #2
Description
Mimo-docker install script will fail if the server has a valid global v6 address but no AAAA record pointing back to it.
The public_ip variable is populated using curl which defaults to v6 if v6 routing is available. Forcing v4 or probing for both address types and prompting the user to update their AAAA records may be more user friendly.
