The nameserver ns.front-data.dk appears in the delegation of 72 .dk domains in our dataset — 0.01% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 3 (4.2%) validate as secure — below the zone-wide average of 62.8%, while 38 (52.8%) are unsigned, with none failing validation outright — a further 31 come back indeterminate.

One thing worth flagging: 31 of these domains (43.1%) 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.
