Normally $25 just now you can upgrade your DYNDNS free account to pro for only $10.
QuoteStarting now, if you would like to maintain your free Dyn account, you must log into your account once a month. Failure to do so will result in expiration and loss of your hostname. This activity helps us eliminate hostnames that are no longer needed and/or dormant. Note that an update client will not suffice for this monthly login.
We understand that the possibility of resulting service interruptions may be frustrating, so we are offering a one-time transition upgrade to VIP status (Dyn Pro) for just $10 USD. Under this status, login will not be required and service will remain uninterrupted for an entire year.
