Domain research

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.

Two abuse reports show where compromised domains concentrate - by domain zone and by registrar - and the Top 1M list ranks the most popular websites on the Internet.

About the data

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: compromised domains, compromised IP addresses.
