The AUTH CODE is typically used to transfer a domain name. This code can be provided by the current registrar of the domain. Alternatively, you could change your domain's nameservers, but that's also something that has to be done through the domain registrar.

The domain registrar is the company through whom you've purchased your domain name. We're not a domain registrar, we're only a hosting provider, so I can't give you your transfer auth code or change your nameservers from my end.

The only exception are the free subdomains we provide. However, free subdomains cannot be pointed to other nameservers or be transferred to other companies. You can migrate our free subdomains to iFastNet, but you'll have to ask iFastNet to pull the subdomains in.
