The nameserver NS2.101DOMAIN.COM appears in the delegation of 381 .dk domains in our dataset — 0.03% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 1 (0.3%) validate as secure — below the zone-wide average of 62.8%, while 372 (97.6%) are unsigned, with none failing validation outright — a further 8 come back indeterminate.

One thing worth flagging: 6 of these domains (1.6%) 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.
