The nameserver ns1.dnsservers.dk appears in the delegation of 350 .dk domains in our dataset — 0.03% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 1 (0.3%) validate as secure — below the zone-wide average of 62.7%, while 270 (77.1%) are unsigned, with none failing validation outright — a further 79 come back indeterminate.

One thing worth flagging: 77 of these domains (22.0%) 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.
