The nameserver ns1.dnsserver.dk appears in the delegation of 6,666 .dk domains in our dataset — 0.50% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 6,574 (98.6%) validate as secure — comfortably above the zone-wide average of 62.8%, while 82 (1.2%) are unsigned, with none failing validation outright — a further 10 come back indeterminate.

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