How we classify
A name takes the row its nameservers match on our provider list. Verification nameservers sit beside a name’s other nameservers, so they overlap the rows above: 0.4%. List 2026.09.7+psl4b673689.

Counted from the registry’s own zone file on the night of Oct 13, 2026. A zone count is not domains under management: a registered name that is not delegated never appears in the zone, and a name on hold leaves the zone while it stays registered. The two numbers will not agree, and neither is wrong.

Aug 2026: 70,969 — third-party estimate; the registry has not published that month yet.

how many names

Names under management at month end, as the registry reported it. Reported to ICANN monthly. Dashed months are third-party estimates. Sunrise Jun 2014 to Aug 2014; general registration Aug 2014.
