- ? Where does the .doctor domain count come from?
- We ingest ICANN CZDS zone files and Certificate Transparency logs continuously and snapshot the per-TLD count once a day. A .doctor domain is counted as active if it appeared in a zone file in the last 2 days, or — where no zone file is published — if a certificate was issued for it in the last 12 months.
