NetAPI tracks hundreds of millions of registered domains across every top-level domain and refreshes the data every day. The reports on this page are built from that data and are free to read, cite and reuse.
The Top 1M list ranks the most popular websites on the Internet, the anatomy report breaks that list down by TLD, DNS provider, hosting country, registrar and domain age, the DNS market share report tracks which providers serve the world's domains and who is gaining ground, and two abuse reports show where compromised domains concentrate - by domain zone and by registrar.
The abuse reports compare the domains currently listed in public threat feeds with the number of active domains in each zone and registrar portfolio, so that large zones are not penalised for their size. The Top 1M list is rebuilt every day from SEO and traffic signals. Every report states the date its data was last refreshed.
The underlying feeds are available as free downloads: Top 1M websites list, compromised domains, compromised IP addresses.
