The nameserver sec1.rcode0.net appears in the delegation of 112 .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, 100 (89.3%) validate as secure — comfortably above the zone-wide average of 62.8%, while 11 (9.8%) are unsigned, with none failing validation outright — a further 1 come back indeterminate.

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