The nameserver ns2.eurodns.com appears in the delegation of 13,607 .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, 5,444 (40.0%) validate as secure — below the zone-wide average of 62.6%, while 7,835 (57.6%) are unsigned, and 10 (0.1%) currently fail validation outright (bogus) — a further 318 come back indeterminate.

One thing worth flagging: 200 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.
