The nameserver b.ns.itafdelingen.net appears in the delegation of 84 .dk domains in our dataset — 0.01% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 5 (6.0%) validate as secure — below the zone-wide average of 62.7%, while 60 (71.4%) are unsigned, with none failing validation outright — a further 19 come back indeterminate.

One thing worth flagging: 18 of these domains (21.4%) 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.
