The nameserver kate.ns.cloudflare.com appears in the delegation of 818 .dk domains in our dataset — 0.06% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 46 (5.6%) validate as secure — below the zone-wide average of 62.7%, while 751 (91.8%) are unsigned, and 2 (0.2%) currently fail validation outright (bogus) — a further 19 come back indeterminate.

One thing worth flagging: 5 of these domains (0.6%) 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.
