The nameserver a1-129.akam.net appears in the delegation of 17 .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, 1 (5.9%) validate as secure — below the zone-wide average of 62.7%, while 2 (11.8%) are unsigned, and 13 (76.5%) currently fail validation outright (bogus) — a further 1 come back indeterminate.

One thing worth flagging: 14 of these domains (82.4%) 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.
