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.
I received an email from dyn.com (aka dyndns.org et al); apparently they're going to free require users to manually login every month or they will expire accounts.
Bill, I wonder if that isn't for new customers. I started free DynDNS service for three MediaSoft dynamic IPs several years ago. At some point, they changed to just offer two for free, but they didn't reduce the MediaSoft account to two. I haven't logged in to DynDNS recently, but all three hosts are still active there, so I don't think the change applies to our use - they play by the "a deal is a deal" rule.
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.
For anyone reading this and wondering how to accomplish what BarryG's doing, the trick is to use a CNAME like myhost.mydomain.com -> myhostmydomain.dyndns.org.
