The nameserver zac.ns.cloudflare.com appears in the delegation of 130 .dk domains in our dataset — 0.01% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 6 (4.6%) validate as secure — below the zone-wide average of 62.7%, while 120 (92.3%) are unsigned, and 2 (1.5%) currently fail validation outright (bogus) — a further 2 come back indeterminate.

Delegation health looks clean, too: none of these domains currently register as lame delegations at this nameserver.
