The nameserver bella.ns.cloudflare.com appears in the delegation of 490 .dk domains in our dataset — 0.04% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 233 (47.6%) validate as secure — below the zone-wide average of 62.7%, while 237 (48.4%) are unsigned, and 10 (2.0%) currently fail validation outright (bogus) — a further 10 come back indeterminate.

One thing worth flagging: 18 of these domains (3.7%) 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.
