The nameserver ns1.fab-it.dk appears in the delegation of 103 .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, 8 (7.8%) validate as secure — below the zone-wide average of 62.7%, while 76 (73.8%) are unsigned, with none failing validation outright — a further 19 come back indeterminate.

One thing worth flagging: 18 of these domains (17.5%) 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.
