Every .dk domain that delegates its _acme-challenge name to 9411f6ea-d704-4d75-ada4-35720202b988.acme-auth.bazo.dk. 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.
