Using Dyn’s dynamic DNS eliminates the headache and human error associated with tracking ever-changing IP addresses and allows you to avoid the alternative of purchasing pricey static IPs.

DynDNS has been around since around 2001. I'de used them as a Dynamic DNS provider since about 2003 or so (have to look at my archives to find out exactly when). Got started with them because they were one of the first DDNS services found in Router firmware. I had my hostname with them for years and years.
This summer, they changed their SLA, and if you didn't visit their site interactively (so they could push ads at you, IMO) you got dropped. SO, I GOT DROPPED. I didn't have email notifications on, but for SUCH A MAJOR POLICY CHANGE, you would think they could have tried.
For many years, my router or net client software kept them happy. But after the SLA change, my router's script visit to update their site failed, and kept failing, because I was stupid and depended on an automation routine to keep things updated, my bad. (Hey, I thought computers were supposed to enable you automate things?!?!!)
I've removed them from my router, left a question in their community about discontinuance best practices, and have come here to Alternativeto.net to find that alternative. I am also a user of OpenDNS.com, which has never given me a problem.
My almost final take on DynDNS? Avoid them because they are going high pressure commercial only, IMO.
This is a mail I received today from DynDNS:
"To our Dyn free hostname users:
For the last 15 years, all of us at Dyn have taken pride in offering you and millions of others a free version of our Dynamic DNS Pro product. What was originally a product built for a small group of users has blossomed into an exciting technology used around the world.
That is why with mixed emotions we are notifying you that in 30 days, we will be ending our free hostname program. This change in the business will allow us to invest in our customer support teams, Internet infrastructure, and platform security so that we can continue to strive to deliver an exceptional customer experience for our paying customers. [...]"
In the comparison of DDNS's DynDNS is pretty much not free anymore. You have to log in INTERACTIVELY every 30 days or less. Router or app based updates don't work anymore.
A few years ago everyone got 5 free DynDNS host names. Since July 2012 also customers who have had many years free host names every 30 days get the following notification by e-mail: Dear Dyn Customer: Your Dyn account 'UserName', has DynDNS free hostname(s) that are due to expire in 5 days. Note that DynDNS free hostnames are deleted after 30 days of inactivity. You can prevent your hostname(s) from expiring here:
https://account.dyn.com/eml/expatconf/n../.....
If you wish to keep your hostname(s) active and not risk missing email notifications like this one, purchase a DynDNS Pro upgrade today.
This is of course very disturbing, so that you can only look for a free DNS service in the future, such as FreeDNS, No-IP, MyBind or BuddyNS.
