The nameserver ns1.yayhosting.dk appears in the delegation of 1,301 .dk domains in our dataset — 0.10% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 693 (53.3%) validate as secure — below the zone-wide average of 62.7%, while 462 (35.5%) are unsigned, and 29 (2.2%) currently fail validation outright (bogus) — a further 117 come back indeterminate.

One thing worth flagging: 139 of these domains (10.7%) 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.
