The nameserver ns1.dns.services appears in the delegation of 7,361 .dk domains in our dataset — 0.55% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 4,192 (56.9%) validate as secure — below the zone-wide average of 62.8%, while 2,989 (40.6%) are unsigned, and 31 (0.4%) currently fail validation outright (bogus) — a further 149 come back indeterminate.

One thing worth flagging: 105 of these domains (1.4%) 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.
