Does anyone aggregate access to all 1500 TLD's? Is there a guide available on which combination of registrars to use to query them all?

  Not all registries participate in the SRS registry protocol. Some of the lesser known ccTLDs must be registered by the individual authorities. It's not accurate to run a DNS query to determine whether the domain is available because one can own the domain, but decide not to set any DNS records.

    Wouldn't non-existent domains just return NXDOMAIN?
    • Ayesh 6y ago
      Yes, but so do registered domains without DNS records.

  Run WHOIS at scale and store the results into a DB. gTLD operators are required to provide WHOIS services, and WHOIS tells you whether any given domain is registered or not. There are companies that will happily sell you this data in a more usable format.
