The nameserver ns1-09.azure-dns.com appears in the delegation of 781 .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, 58 (7.4%) validate as secure — below the zone-wide average of 62.7%, while 636 (81.4%) are unsigned, and 1 (0.1%) currently fail validation outright (bogus) — a further 86 come back indeterminate.

One thing worth flagging: 79 of these domains (10.1%) 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.
