The nameserver ns1.dlx.dk appears in the delegation of 1,532 .dk domains in our dataset — 0.11% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 232 (15.1%) validate as secure — below the zone-wide average of 62.6%, while 1,157 (75.5%) are unsigned, with none failing validation outright — a further 143 come back indeterminate.

One thing worth flagging: 129 of these domains (8.4%) 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.
