Hello! I would like to know, is storage space for my domain https://therealvanyek.ml (registrated in freenom) actually unlimited, as shown in DirectAdmin? Or does it depend on registrar?
What you see there means the domain itself doesn't have a specific limit set within the account, it is still in the end limited to the actual account limit.
For example, say you had account and was reselling parts, you could set a limit to how much that domain (subaccount) was allowed to use.
Just to be clear, with free hosting you can absolutely not re-sell or give away hosting, but with paid plans you can.
