Name Servers which are registered under your domain name are called Child Name Servers.
After you must register Name Servers, you can use them as Name Servers to  register other domain names.
Child Name Servers can only be registered by the owner of the domain that they are registered.
For example;
A Child Name Server ns1.atakdomain.com can only be registered by the owner of atakdomain.com.
