The nameserver ns.gpserver.dk appears in the delegation of 533 .dk domains in our dataset — 0.04% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 10 (1.9%) validate as secure — below the zone-wide average of 62.7%, while 294 (55.2%) are unsigned, and 1 (0.2%) currently fail validation outright (bogus) — a further 228 come back indeterminate.

One thing worth flagging: 226 of these domains (42.4%) 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.
