Most .dk zones rarely change. This list shows the ones that change constantly, counted from the SOA serial changes our scanners record. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.
Every full scan we store means the zone's SOA serial changed, i.e. its owner edited DNS. These are the 200 zones with the most changes in the last 30 days: often dynamic DNS, ACME DNS-01 certificate renewals or automated deployments.
