The nameserver ns2.dotserv.com appears in the delegation of 3,419 .dk domains in our dataset — 0.26% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 30 (0.9%) validate as secure — below the zone-wide average of 62.8%, while 3,186 (93.2%) are unsigned, with none failing validation outright — a further 203 come back indeterminate.

One thing worth flagging: 149 of these domains (4.4%) 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.
