Some people get confused by what is meant by assigning name servers, this is NOT simply a redirect service, the domain will technically act just like as if you had registered it directly with us and can be used as a fully functional domain on our servers and use all of our hosting services.
You will be able to use our control panels to configure Web, FTP, Email and even edit DNS records for the domain.
The domain registrar is then simply responsible for renewal and managing the domain contact records.
