Note: Domain-name statistics vary across organizations because they can only be estimated. Each TLD is run by a registry, and registries publish registration data with very different levels of detail and frequency. Daily registrations and deletions can also swing sharply due to pricing changes, promotions, policy updates, eligibility rules, or enforcement actions.
