The nameserver ns3.dnsservers.dk appears in the delegation of 312 .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 270 (86.5%) are unsigned, with none failing validation outright — a further 41 come back indeterminate.

One thing worth flagging: 39 of these domains (12.5%) 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.
