The nameserver ns4.gigahost.dk appears in the delegation of 16,333 .dk domains in our dataset — 1.22% 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 62.5%, while 15,837 (97.0%) are unsigned, with none failing validation outright — a further 496 come back indeterminate.

One thing worth flagging: 473 of these domains (2.9%) 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.
