      Hi, I am hosting a minecraft server on my pc which only has a DSLite connection.
      I have port forwarding enabled and the server is reachable via its ipv6 address.

      Instead of entering the IP address, I have bought a domain where the AAAA-Record points to my ipv6 address. I also have a srv record pointing to the correct port.

      Since I don't have a static ipv4 address, I chose the ipv4 address from my other server, which is hosted elsewhere, for the A-Record.

      The SRV Record doesn't work, when only ipv6 is available, it seems like minecraft only tries to connect via ipv4, without ever trying to connect via ipv6.

      I know this because if I change the SRV record to point to the port of the other (ipv4) server, it suddenly works, but if I change it back, it is broken again.
