unfortunately, cargo support is a tragedy.the support claims you have to use the cargo nameserver.The cargo nameserver (08-2024) still do not support IPv6 records!!! but we have to use these nameserver???cargo 2 also works with external nameservers.your support should be better trained.The fact that IPv6 does not work is not acceptable if you force your customers to use your nameservers.I have not received any feedback for more than 4 days in which I pointed out the IPv6 problem.
