The nameserver dns1.cscdns.net appears in the delegation of 5,266 .dk domains in our dataset — 0.40% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 301 (5.7%) validate as secure — below the zone-wide average of 62.7%, while 4,840 (91.9%) are unsigned, with none failing validation outright — a further 125 come back indeterminate.

One thing worth flagging: 68 of these domains (1.3%) 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.
