Every .dk domain that delegates its _acme-challenge name to 5daa24b8-e614-4c96-9d94-3f2772c317d6.acme.educant.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.
