The Nameserver Predelegation Check for the dynv6 nameservers fails for my domain
https://www.denic.de/service/tools/nast/
output looks like the following:
|Error|901|Unexpected RCODE (target, entity, RCODE)
- ns1.dynv6.com./95.216.144.82:53
- henninghäcker.de
- NXDOMAIN|
| — | — |
Doing the check with the punycode representation (henninghäcker.de) yields exactly the same output.
However for other nameservers this works fine.
Since this a requirement for some domain providers to update the name servers it would be cool to get this fixed.
Is this really a nameserver issue, if yes: can it be fixed in the foreseeable future?
Thank you very much in advance!
