nTLDData legacy TLDs too :)

Registry backends

Which technical registry service provider actually serves each new gTLD's DNS. ICANN publishes no TLD-to-backend mapping, so this is inferred from three signals: the root-zone nameserver hostnames, the RDAP endpoint from IANA's bootstrap file, and — for TLDs running vanity hostnames — the reverse DNS of those nameservers' addresses.

New gTLDs Legacy gTLDs All gTLDs
1,090 TLDs attributed across 26 platforms. 24 remain unattributed — brand TLDs whose vanity nameservers and RDAP endpoints reveal nothing about who operates them. They are counted here rather than quietly dropped. How the inference works.

Backend concentration

Source: ICANN monthly registry reports

A handful of platforms serve the DNS for most of the new-gTLD namespace. Share of all new-gTLD domains by technical backend, from ICANN's monthly registry reports. Each TLD is attributed to the platform serving it today — nothing records who ran a TLD's DNS in 2016 — so this is volume on today's platforms over time, not who served it at the time.

Data currency. Domain counts on this page are from zone files dated and refresh daily. Registrar figures are from ICANN's monthly registry reports for May 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
