The nameserver nonexistent.punktum.dk appears in the delegation of 40,886 .dk domains in our dataset — 3.06% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 0 (0.0%) validate as secure — below the zone-wide average of 62.5%, while 1 (0.0%) are unsigned, with none failing validation outright — a further 40,885 come back indeterminate.

One thing worth flagging: 40,690 of these domains (99.5%) 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.
