The nameserver blue.foundationdns.com appears in the delegation of 289 .dk domains in our dataset — 0.02% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 191 (66.1%) validate as secure — comfortably above the zone-wide average of 62.7%, while 98 (33.9%) are unsigned, with none failing validation outright.

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