The nameserver ns4-09.azure-dns.info appears in the delegation of 779 .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, 56 (7.2%) validate as secure — below the zone-wide average of 62.6%, while 635 (81.5%) are unsigned, and 1 (0.1%) currently fail validation outright (bogus) — a further 87 come back indeterminate.

One thing worth flagging: 80 of these domains (10.3%) 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.
