The nameserver blue.foundationdns.org appears in the delegation of 290 .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, 190 (65.5%) validate as secure — comfortably above the zone-wide average of 62.5%, while 100 (34.5%) are unsigned, with none failing validation outright.

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