Every .dk domain that delegates its _acme-challenge name to e8360ec8-72cc-40cb-99f7-8ea188f03fc8.6.authorize.certificatemanager.goog. 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.
