The nameserver irena.ns.cloudflare.com appears in the delegation of 102 .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, 3 (2.9%) validate as secure — below the zone-wide average of 62.7%, while 99 (97.1%) are unsigned, with none failing validation outright.

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