Domain Insights

A view across the domains in our dataset — who registers them, who runs their DNS, and which corners of the namespace people actually keep.

Registrar market share

Share of domains held by each registrar.

Curious about a specific registrar? Browse every IANA registrar or search one by ID.

Share of domains grouped by their nameserver operator.

Want to see which nameservers a domain uses — or what else runs on a given nameserver? Try a nameserver lookup.

Share of sites by the web server software behind them.

See the DNS and hosting records behind any site with a DNS lookup.

Share of domains by top-level domain.

Look up any domain, in any TLD, with a WHOIS lookup.

Each bubble is a TLD (size = its share of domains). Bottom-left = cheap, short-lived, quickly-abandoned TLDs; right = domains people hold for years.

Watch the churn live on the recent domain events page — new registrations, expirations, and drops.

* Figures are estimates based on a large sample of domains in our dataset.
