The nameserver justin.ns.cloudflare.com appears in the delegation of 956 .dk domains in our dataset — 0.07% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 428 (44.8%) validate as secure — below the zone-wide average of 62.6%, while 518 (54.2%) are unsigned, with none failing validation outright — a further 10 come back indeterminate.

One thing worth flagging: 7 of these domains (0.7%) 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.
