DynDNS does still offer the free service, but you are required to sign up for a 30 day trial of Pro, first. Sad end of an era.
I just checked and it looks like its a 14 day trial now, but you can keep a domain name for free after the trial.
I'm guessing you need a credit card to set up your account, and then you need to remember to cancel it to not be charged...
Well, still better than no free option anymore..
From the site:
-----------------------------
When the trial ends After the 14 day trial, you will be charged our low yearly fee of just $20 a year (or sign up for five years and get 10% off!) to keep your DynDNS Pro service. Only valid major credit cards (not PayPal) are accepted for DynDNS Pro trials.
Decide you no longer want the DynDNS Pro trial? Just cancel your DynDNS Pro trial within 14 days and you will not be charged. You may keep one hostname free of charge for trying out the DynDNS Pro trial.
