IPv6 / AAAA Troubleshooting Warning
As a WHM administrator I would like for cPanel and / or WHM to display a warning when a domain has a AAAA record configured in DNS, but does not have IPv6 enabled for the account.
I would like this feature because it can be easy to overlook or forget about a AAAA record when troubleshooting. If the account does not have IPv6 enabled, the presence of a AAAA can be a troublesome issue to troubleshoot if you've not noticed that the AAAA record is in place.
A specific example is that AutoSSL will fail to issue certificates for a domain if it has a AAAA record in place, but does not have IPv6 enabled via WHM. It takes experience or a lot of troubleshooting to connect the resulting 404 error with the fact that IPv6 is disabled.
