The nameserver ns3.netsite.se appears in the delegation of 6,309 .dk domains in our dataset — 0.47% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 6,161 (97.7%) validate as secure — comfortably above the zone-wide average of 62.8%, while 143 (2.3%) are unsigned, and 5 (0.1%) currently fail validation outright (bogus).

One thing worth flagging: 4 of these domains (0.1%) 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.
