out of query targets -- returning SERVFAIL

[Havard Eidnes]

Hmm...

>     # nslookup dennikn.sk. 10.0.0.2

Friends don't let friends continue to use "nslookup".
Use "dig" instead.

With that said, someone was at dnsviz.net 41 minutes ago testing,
ref.

  https://dnsviz.net/d/dennikn.sk/dnssec/

but there's only warnings about the .SK name servers and missing
DNS cookies for DNSKEY queries, and that should not (?) cause
this issue.

Best regards,
