Sources and methodology

TLD inventory

Delegated TLD names come from IANA’s versioned delegated TLD list (Version 2026092800, Last Updated Mon Sep 28 07:07:02 2026 UTC). Each TLD page links to its IANA Root Zone Database record.

TLD types, managers, and Brand records

IANA classification and manager data are refreshed from the Root Zone Database. Active Brand records are refreshed from ICANN Registry Agreements marked Brand (Spec 13). Some delegated names may not have a current IANA type row; those appear as unclassified. Topic groups are editorial examples, overlap, and are not official labels or a complete taxonomy.

Registrar coverage and prices

The registrar baseline is the ICANN-accredited gTLD directory. It does not include every ccTLD-only provider, retail brand, or reseller. Prices and offers are published only with a recorded primary source, currency, and observation time; unknown values remain unknown.

Launch dates

Sunrise, landrush or early access, and general availability are recorded only from official registry sources. IANA delegation alone does not prove a public launch date.

Affiliate links

Affiliate destinations are used only after approval. Otherwise registrar links use their native destination. Affiliate status does not affect comparison order or price facts.

Version history

Source versions and observation dates are retained by the writer. Price history will use dated observations with source evidence.
