The nameserver ns4.dk appears in the delegation of 1,151 .dk domains in our dataset — 0.09% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 53 (4.6%) validate as secure — below the zone-wide average of 62.7%, while 870 (75.6%) are unsigned, with none failing validation outright — a further 228 come back indeterminate.

One thing worth flagging: 222 of these domains (19.3%) 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.
