Hello, when pointing a .de domain to your NS Servers I get errors. All your NS Servers provide me with the following error:
Inconsistent set of NS RRs

Do you have any solution present for this?

Best regards,
Manuel Bacso

'Inconsistent set of NS RRs' means that the nameserver entries (NS records) in the DNS entry for the corresponding domain do not match the nameservers specified for the domain.

We have customers with .de domain names setting up our name servers without any issues, so it should not be an issue with our name servers. We suggest that you contact your domain registrar for assistance.

Sorry for unearthing that thread but I got the same issue now.
When trying to set the nameservers to ns10 and ns11, the german authority DENIC refuses the edit with the mentioned error.
This is because ns10 and ns11 just declare ns1 to ns6 as nameservers, but not each other (ns7 to ns12). The german authority requires all given nameservers to match the servers returned in the NS section of every given server to be accepted as nameservers. This is crappy and complex (so very german :D)
Do you have any idea to get this working?
One option would be that every NS of Dynu declares all other NS (huge NS section in) or having two servers which just return each other and not all the other ones (complicated setup...)
Would be a pitty having to use servers in the US for a german domain because the query time is MUCH faster. 30msec vs 170msec...
The only option right now s to specify exactly ns1 to ns6, not more and not less to get it accepted by DENIC

You can go to the Control Panel->DDNS Services->youdomain.de->Name Servers section and list ns1, ns10 and ns11 as name servers (default is ns1-ns6). This is how you control what name servers to use at Dynu. Then you list ns1, ns10 and ns11 at your registrar. ns1 is needed as it is the primary name server.

Oh now I get how Dynu works :D
I now removed all NS entries and entered ns10 and ns11 (not ns1) and DENIC accepted the change. Wonderful :)
Thanks for your help!
