Disable DNS IPv6 requests

Configuration
1

Hi all out there,

I’m working with HASS-OS based on Proxmox - see also:

Wthin this, I have disabled IPv6 on all interfaces. This applies to Proxmox as well HASS.

Yet HASS-OS makes every request twice - one time based on IPv4 and a second time based on IPv6.
In addition, ssh seems to be available via ipv6 (see the last line from the listen ports).
Is there a way to disable/stop this?

Rationale:
While the DNS-server can easily handle the additional load/overhead, it doesn’t make any sense. Especially since that IPv6 is disabled on all interfaces.

With warm regards - Will
