A lot of tlds don&#x27;t provide zone files unless you are a registrar. They would probably not be happy if someone put those out to the pubic. For com and the likes they would probably not care as much.<p>The best public list of domains I have found is the Project Sonar DNS (ANY) scans. I don&#x27;t know how they do it, but their scans are pretty complete, at least for.dk domains, which are the ones I use.<p><a href="https:&#x2F;&#x2F;scans.io&#x2F;study&#x2F;sonar.fdns" rel="nofollow">https:&#x2F;&#x2F;scans.io&#x2F;study&#x2F;sonar.fdns</a>
