The nameserver ns1.ascio.net appears in the delegation of 1,064 .dk domains in our dataset — 0.08% 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 0 (0.0%) are unsigned, and 1 (0.1%) currently fail validation outright (bogus) — a further 1,063 come back indeterminate.

One thing worth flagging: 1,063 of these domains (99.9%) 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.
