I have a .dk domain on which I have created a subdomain at desec.io.
So on desec.io, I do have my real domain, lets say, example.dk. I have configured this domain for DNSSEC.
So far so good.
Now, I also have subdomain, lets say, sub.example.dk.
I now get a warning email from firstname.lastname@example.org telling me that I need to configure DNSSEC for sub.example.dk. However, I can’t, because on punktum.dk (hostmaster for .dk TLD) I can only register DNS sec keys for the actual .dk domain, not subdomains.
So what am I to do?
Please note that when I say a subdomain, I do not mean that I just created a record for sub.example.dk Instead, I created sub.example.dk as a separate domain in desec Domain Management interface.
The reason I did this is that I use this subdomain for various dynamic DNS stuff and administer this subdomain via desec API, while I manage the parent domain manually via mangement interface.
