Can a domain name registered elsewhere use your system to register new nameservers?
No, you must register your domain name through us to use our system to register nameservers for it. For domain names registered elsewhere, you must register nameservers through your current registrar.
For more information, contact your current registrar.
If you registered nameservers through our system, you can assign them to domain names registered elsewhere. See Change nameservers for my domains for more information.
