The nameserver ns1.eurodns.com appears in the delegation of 13,621 .dk domains in our dataset — 1.02% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 5,447 (40.0%) validate as secure — below the zone-wide average of 62.7%, while 7,838 (57.5%) are unsigned, and 10 (0.1%) currently fail validation outright (bogus) — a further 326 come back indeterminate.

One thing worth flagging: 201 of these domains (1.5%) 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.
