Market share reports

DomainLists is a TLD zone-file feed with over 1,287 gTLDs and ccTLDs available and daily updated. They are available as simple CSV downloads and APIs for integration into your application. We use a sophisticated process of parsing zone files for Generic Top Level Domains (gTLDs) and recreating country code Top Level Domains (ccTLDs). Many domain registries don’t distribute complete zone files so we process lots of data to recreate domains.
