The count follows what webXtrend knows, not the registry's own books. Figures before 2023 are left out because our coverage was still being built up then, and a step in the curve can come from a change in coverage rather than in the zone.

The full domain list export contains every .phd domain webXtrend knows, 2,540 today. New .phd domains come every day with the daily new-domain file, together with all other TLDs, and the API answers for any single domain: DNS history, redirects, reverse IP and the start page.

Counts are the domains webXtrend knows, from its own measurement of the public domain name space. They are not the registry's figures: where a registry does not publish its zone, our count can be lower than its own. Registry facts come from the IANA root zone database.
