Problem with the domain

domain-name-system

I have a domain (.se) that I have "own" for years, I've been pointing
out a dyndns domain as the nameserver for my .se domain to be able to use my top domain
with a dynamic ip internet connection. This has been working for over 5 years, but now It has stopped working

The DNSCheck v1.0.1 response is this:

No name servers found at child.
Superfluous name server listed at parent:
A name server listed at the parent, but not at the child, was found. This is most likely an administrative error. You should update the parent to match the name servers at the child as soon as possible.

How do I resolve this?

Edit:

This is how it's setup:

domain.se NS domain.mine.nu

There is NO dns-server running on domain.mine.nu and have never been.
And thats it, it has worked flawlessly for over 5 years, but now it has stoped, can anyone figure out why?

Best Answer

This means that your nameservers (NS records) are not in the zone configured on your DNS server.

You should be able to do:

$ dig yourdomain.se NS @yourdnsmaster

and get NS records as a result.
