Hi,

We can host any domain, so yes you can use .ba but you would need to have the domain registered through a registrar that handles the .ba extension.

You are not required to purchase a domain from us to have a hosting plan, if your domain is already registered you can simply use the I already have a domain option during sign up.  If, the domain is not registered you will want to find a registrar that can register the domain first then, apply for a hosting plan.
