The nameserver lina.ns.cloudflare.com appears in the delegation of 280 .dk domains in our dataset — 0.02% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 71 (25.4%) validate as secure — below the zone-wide average of 62.7%, while 208 (74.3%) are unsigned, and 1 (0.4%) currently fail validation outright (bogus).

One thing worth flagging: 1 of these domain (0.4%) 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.
