This is amazing. I didn't know this sort of list can be created. I haven't subscribed for a paid plan but I know I will spend time just browsing and analyzing... what is the source of this information?
Thank you! Glad you find it interesting - it’s definitely fun (and sometimes surprising) to explore how the domain landscape evolves. I don’t publicly share specific data sources, but creating and maintaining a comprehensive list across 1570+ zones involves a mix of aggregation, normalization, and ongoing reconciliation work. Domain data is updated daily. AllZoneFiles.io is here to save you a ton of time and effort on that, so that you be able to easily get the latest, fullest and most up-to-date domain data anytime you need it.
