      When using a DDNS service, i can't get Minecraft to connect to my server using IPV6. It does not connect on the PC hosting, another PC on the same network, or my friend's PC across the internet.

      Connecting from a direct IPV6 address works in all cases, and using No-IP's DDNS service works with an IPV4 address, but not an IPV6 address.

       

      This is not an issue with the firewall, Windows Defender's firewall was turned off during testing. I have made sure that the DDNS address functions as should.
