What is the impact of second-level registrations on third-level registrations (or, “how does it work?”)?
If someone has registered a second-level domain, such as smith.name, then no one can register a third-level domain, such as john.smith.name. The reverse is also true: If someone has registered a third-level domain, such as john.smith.name, then no one can register a second-level domain, such as smith.name.
