I have a concern, so far I have only used IPv4, then today I created all AAAA records and tested the installation, everything works as intended.
Also the DNS test in the panel is all on green.
The cow installation is all on default, no custom modifications.
Is there anything that needs to be modified for the complete IPv4 and IPv6 dual-stack operation?
When I send a mail, for example, the IPv4 address is still in the header, maybe this is normal?
Could not find any info on this 🙂
Maybe I still have to adjust something, would be very grateful for a hint.
