The nameserver ns2.quickdns.dk appears in the delegation of 1,098 .dk domains in our dataset — 0.08% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 6 (0.5%) validate as secure — below the zone-wide average of 62.8%, while 1,016 (92.5%) are unsigned, with none failing validation outright — a further 76 come back indeterminate.

One thing worth flagging: 62 of these domains (5.6%) 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.
