The nameserver ns06us.sac-it.dk appears in the delegation of 292 .dk domains in our dataset — 0.02% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 1 (0.3%) validate as secure — below the zone-wide average of 62.7%, while 290 (99.3%) 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.
