The nameserver oswald.skole.cloud appears in the delegation of 10 .dk domains in our dataset — <0.01% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 7 (70.0%) validate as secure — comfortably above the zone-wide average of 62.7%, while 2 (20.0%) are unsigned, and 1 (10.0%) currently fail validation outright (bogus).

Delegation health looks clean, too: none of these domains currently register as lame delegations at this nameserver.
