Starting 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 using an update client will no longer suffice for this monthly login.
Also, I'm thinking of buying a domain, but I'd still like to have some way of updating it dynamically since I don't have a static IP.
