The nameserver ns2.icp100.net appears in the delegation of 82 .dk domains in our dataset — 0.01% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 0 (0.0%) validate as secure — below the zone-wide average of 62.7%, while 45 (54.9%) are unsigned, with none failing validation outright — a further 37 come back indeterminate.

One thing worth flagging: 35 of these domains (42.7%) 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.
