Legacy gTLD statistics
Daily domain counts, registrar market share, registry backends and DNSSEC adoption across 18 legacy generic top-level domains, built entirely from ICANN and IANA public data.
A further 1 legacy gTLDs hold 284 domains that are not in this total: we have no zone file for them, so they are only visible in their registries' monthly reports. Both clocks explained.

Data currency. Domain counts on this page are from zone files dated and refresh daily. Registrar figures are from ICANN's monthly registry reports for May 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
