The nameserver ns2.telanco.dk appears in the delegation of 705 .dk domains in our dataset — 0.05% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 3 (0.4%) validate as secure — below the zone-wide average of 62.7%, while 672 (95.3%) are unsigned, with none failing validation outright — a further 30 come back indeterminate.

One thing worth flagging: 14 of these domains (2.0%) 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.
