Thanks for the hints. I’m interested in collecting all sites/domains for a specific ccTLD (.gr) purely for statistics/curiosity. I know that some countries publish their zones files, but for the GR registry (like many other countries) this is not available. I’m not interested in the WHOIS data, sine as you correctly mention contain sensitive data. I was thinking that somehow if I had my own DNS server I would be able to download all available domains, but after some reading I understood that this is not how DNS servers work. A request from a local client (inside my own LAN) would need to perform an nslookup or web access for each domain, so that the result could be cached.
