The nameserver pns43.cloudns.net appears in the delegation of 631 .dk domains in our dataset — 0.05% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 20 (3.2%) validate as secure — below the zone-wide average of 62.8%, while 597 (94.6%) are unsigned, with none failing validation outright — a further 14 come back indeterminate.

One thing worth flagging: 17 of these domains (2.7%) look like lame delegations — the .dk registry still points them here, but this nameserver doesn't answer authoritatively for the zone, which usually means the hosting was cancelled and the delegation was left dangling.
