You can register .ro domains and every Romanian extension (.com.ro, .info.ro, .org.ro, .store.ro and more), plus international ones such as .com, .net, .org, .e...
For a DNS record's name, should I enter @, the full domain or just the subdomain?
It depends on the format expected by the form where you add the record. The symbol “@” usually represents the domain itself, without a subdomain. For a subdomain such as “shop.example.ro”, some forms require just “shop”, while others accept the full name.
Read the field instructions before saving: if the domain is appended automatically, entering the full name could accidentally create “shop.example.ro.example.ro”. After saving, check the resulting name in the record list. Do not assume that “@” works the same way in the name and destination fields; those fields serve different purposes.
