The nameserver pns64.cloudns.uk appears in the delegation of 18 .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, 3 (16.7%) validate as secure — below the zone-wide average of 62.7%, while 15 (83.3%) are unsigned, with none failing validation outright.

One thing worth flagging: 1 of these domain (5.6%) 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.
