The nameserver ns4.eastman.com appears in the delegation of 5 .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, 0 (0.0%) validate as secure — below the zone-wide average of 62.7%, while 5 (100.0%) are unsigned, with none failing validation outright.

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