The nameserver dns01.dipcon.com appears in the delegation of 2,355 .dk domains in our dataset — 0.18% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 57 (2.4%) validate as secure — below the zone-wide average of 62.8%, while 2,106 (89.4%) are unsigned, with none failing validation outright — a further 192 come back indeterminate.

One thing worth flagging: 169 of these domains (7.2%) 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.
