The nameserver ns4.bdm.microsoftonline.com appears in the delegation of 2,380 .dk domains in our dataset — 0.18% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 12 (0.5%) validate as secure — below the zone-wide average of 62.7%, while 2,316 (97.3%) are unsigned, and 1 (0.0%) currently fail validation outright (bogus) — a further 51 come back indeterminate.

One thing worth flagging: 16 of these domains (0.7%) 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.
