I'm looking to extend the amount of time that my domain name is registered for.
On the page https://www.dynadot.com/account/domain/name/edit.html?domain_id=3041952 it gives me the option to 'Renew Domain'.
Will undertaking this option directly alter the expiration date as shown on the same page, or will it be treated as a 'prepayment' for when the domain expires (and thus creating a new registration)?
