How hard is it to transfer a domain such as .AD to godaddy? Even though they don't provide it as a registration (then how would you renew it?) Thanks.
It might be impossible - from what I can tell, GoDaddy do not offer a registration or transfer service for Andorran domains (in fact the only ccTLDs that they offer transfers for are .US, .CC, .TV and .EU).
You won't be able to transfer .ad domains to Godaddy or any other extentions that are not supported by them. You can only transfer it to another registrar that supports that extention, & only if .ad names are allowed to be transferred, as I know some extentions are not allowed to be transferred to other companies (I think .gs is one of them).
