Remember: the domain name system is hierarchical. When you register a domain name, the domain registry (that is, the entity that manages delegating domain names in a particular top-level domain name, or TLD, also sometimes referred to more colloquially as an extension or domain ending) delegates the authority over the DNS zone of that domain name to you.

You might also be hoping to get full list of all the services a domain name points to, for example, to transfer it to another DNS provider. There are several reasons you might want to be able to find all subdomains of a domain, but in general, those reasons boil down to either mounting some kind of attack on a website (which we don’t condone) or protecting yourself from such an attack, including auditing your subdomains to ensure there are no unused subdomains laying around in your DNS zone file.
