Every .dk domain whose A record resolves to 64.20.40.243. Shared-hosting servers often carry hundreds of sites on one address; this reverse IP lookup shows exactly which .dk names share it. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.

The zone shown is the most specific level that answers an NS query, so a classless delegation may report its parent.
