The nameserver ns3.dns-reg.com appears in the delegation of 14 .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, 11 (78.6%) validate as secure — comfortably above the zone-wide average of 62.7%, while 3 (21.4%) are unsigned, with none failing validation outright.

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