The nameserver ns1.curanet.dk appears in the delegation of 55,887 .dk domains in our dataset — 4.18% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 52,253 (93.5%) validate as secure — comfortably above the zone-wide average of 62.5%, while 782 (1.4%) are unsigned, and 2,062 (3.7%) currently fail validation outright (bogus) — a further 790 come back indeterminate.

One thing worth flagging: 2,799 of these domains (5.0%) 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.
