The nameserver dns2.dk appears in the delegation of 150 .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, 131 (87.3%) validate as secure — comfortably above the zone-wide average of 62.8%, while 0 (0.0%) are unsigned, and 6 (4.0%) currently fail validation outright (bogus) — a further 13 come back indeterminate.

One thing worth flagging: 19 of these domains (12.7%) 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.
