Interpret carefully
Limits that affect the decision
IANA's data identifies TLD delegation and RDAP service locations, not guaranteed availability or completeness of each registry/registrar's response; downstream RDAP servers remain operational dependencies.; The root zone and RDAP bootstrap registry are global Internet registries, but they identify delegated TLDs and authoritative RDAP services; they do not provide complete end-user DNS resolution or registrar customer data.; The JSON registry is versioned/published and can change as delegations and RDAP services change; consumers should refresh rather than assume a permanent mapping.
Release cadence was not normalized in this review; check the source's dates, update notes, and API limits before comparing periods.
