The nameserver ns2.bdm.microsoftonline.com appears in the delegation of 2,387 .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, 14 (0.6%) validate as secure — below the zone-wide average of 62.7%, while 2,318 (97.1%) are unsigned, and 1 (0.0%) currently fail validation outright (bogus) — a further 54 come back indeterminate.

One thing worth flagging: 19 of these domains (0.8%) 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.
