The nameserver ns2.ryg.braathe.no appears in the delegation of 24 .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, 21 (87.5%) validate as secure — comfortably above the zone-wide average of 62.7%, while 2 (8.3%) are unsigned, and 1 (4.2%) currently fail validation outright (bogus).

One thing worth flagging: 1 of these domain (4.2%) look like lame delegations — the .dk registry still points them here, but this nameserver doesn't answer authoritatively for the zone, which usually means the hosting was cancelled and the delegation was left dangling.
