The nameserver ns2.jetcom.dk appears in the delegation of 235 .dk domains in our dataset — 0.02% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 6 (2.6%) validate as secure — below the zone-wide average of 62.8%, while 219 (93.2%) are unsigned, and 1 (0.4%) currently fail validation outright (bogus) — a further 9 come back indeterminate.

One thing worth flagging: 7 of these domains (3.0%) 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.
