2026 strings our model compared with it

When we scored the 2026 round, our model listed .icu among the closest 2012-round TLDs for 12 applied-for strings. No applicant made these comparisons; strong and moderate are how close it judged each match.

Cross-checkThe registry reported 502,608 names for Apr 2025; the zone on Oct 24, 2026 held 52,510 more. The two are counted differently and 18 months apart: a registered name that is not delegated never appears in the zone, and a zone file is read on one night, a report at a month's end.

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: 0.0%. List 2026.09.7+psl4b673689.

Counted from the registry’s own zone file on the night of Oct 24, 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.
