Hello @Luis Zubeldia.
Disabling or enabling BIND lookups for IPv6 is a purely optional step and depends on the exact use case.
It is not related to enabling IPv6 functionality for the system.
In order to completely disable BIND lookups for IPv6, it is required to start BIND with "-4" option and enable "filter-aaaa-on-v4" in BIND configuration. It is not recommended by BIND developers though.
Locations for configuration files where options should be specified may vary depending on the operating system. Please refer to BIND manual and the documentation for the operating system in use.
I did follow this tutorial, but the ipv6 connectivity still fail...
I restart the server, tried to delete the ipv6 adresses and put it back again, but it didn't fix the problem...
Any idea to solve the problem?
PS : I'm using CentOS Linux 7.9.2009 (Core), Plesk Obsidian 18.0.32
