The nameserver ns3-04.azure-dns.org appears in the delegation of 825 .dk domains in our dataset — 0.06% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 77 (9.3%) validate as secure — below the zone-wide average of 62.7%, while 677 (82.1%) are unsigned, with none failing validation outright — a further 71 come back indeterminate.

One thing worth flagging: 60 of these domains (7.3%) 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.
