Registrar profiles show which .dk domains a registrar manages in our WHOIS sample, how they score on DNSSEC, IPv6 and mail security, how fast they resolve and what a .dk domain costs there. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.
Counts domains in our WHOIS sample, not the registrar’s full book. The sample is still growing, so a rising line here is partly wider coverage rather than domains transferring in.
