When i am trying to just use wildcard for IPv4 and Use IPv6 through my ISConfig3 Panel on a host that is IPv6 Enabled. I am enabling LetsEncrypt SSL and it all is showing fine in vhost file and it also resolves on various DNS checking tools. But the website does not show. For website to resolve i have to use IPv4 along with IPv6 Entry. My question is : HOW CAN I JUST USE IPV6 WITHOUT USING THE IPV4 SO ALL MY WEBSITES HAVE UNIQUE IPV6 INSTEAD OF SAME IPV4 ? Do let me know if i need to configure anything else. I am not modifying the Vhosts files manually.
