The nameserver linux3.dform.dk appears in the delegation of 24 .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, 0 (0.0%) validate as secure — below the zone-wide average of 62.8%, while 23 (95.8%) are unsigned, with none failing validation outright — a further 1 come back indeterminate.

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