A top-level domain (TLD) is the last segment of a domain name — the part that follows the final dot. In example.com, the TLD is .com. TLDs sit at the highest level of the Domain Name System (DNS) hierarchy and are managed by registry operators under the coordination of the Internet Corporation for Assigned Names and Numbers (ICANN). As of 2026, there are 1,936 active TLDs in the root zone, operated by 888 registry organizations worldwide. TLDs are categorized into generic TLDs (gTLDs) like .com and .org, country-code TLDs (ccTLDs) like .uk and .jp, brand TLDs owned by corporations, and sponsored TLDs managed by specific communities. This directory tracks every active TLD with daily-updated zone file analytics, registrar pricing comparison, and DNSSEC adoption data.

1,133 TLDs have registrar pricing data available for comparison. Data is sourced from TLD zone files analyzed daily and registrar pricing feeds updated hourly.
The DNSChkr TLD Directory is built from multiple authoritative data sources, refreshed on automated schedules to maintain accuracy. Zone file data — the authoritative DNS records published by each TLD registry — is downloaded and parsed daily to compute domain registration counts, DNSSEC adoption rates, DNS provider market share, and namespace density analytics. Registrar pricing is aggregated hourly from registrar APIs to track registration, renewal, transfer, and restore costs across providers. Registry operator information is sourced from IANA and ICANN delegation records. Each TLD page combines this data with AI-generated educational content covering history, use cases, registration requirements, and security features. All data points include the date of last update so users can verify freshness.
