The nameserver ns1.shellhost.dk appears in the delegation of 450 .dk domains in our dataset — 0.03% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.

On the DNSSEC side, 208 (46.2%) validate as secure — below the zone-wide average of 62.8%, while 240 (53.3%) are unsigned, with none failing validation outright — a further 2 come back indeterminate.

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