Every .dk domain that delegates its _acme-challenge name to bfed43f7-7903-457c-95b1-671f0a08ba4f.germanywestcentral.cloudapp.azure.com. Such CNAMEs hand DNS-01 certificate validation to a shared service, so this list shows who issues TLS certificates through it. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.
