How can I change the Name Server information for my Domain Name?
At most domain registrars, the Registrant, Administrative Contact, and Technical Contact are the only people who have authority to modify information regarding the domain name - including the DNS or nameserver information.
If you are one of the 'titles' above, you can go to website where you registered the Domain Name and login to begin the process. From there, follow the online directions the registrar gives you in order to edit the Name Server information.
