DynDNS invented the dynamic DNS protocol in the 1990s. After being acquired by Oracle/Dyn, it became an enterprise product with no free tier and pricing aimed at large organisations. It is no longer a practical option for individuals or small businesses.
In May 2014, Dyn (now Oracle) shut down its free dynamic DNS service, leaving millions of users scrambling for alternatives overnight. Today DynDNS is exclusively an enterprise product with pricing that reflects that — think hundreds to thousands of dollars per year, not $5/month.
The DynDNS update protocol is the industry standard that virtually every router and firmware supports. NovaDNS is fully compatible with this protocol — you can point any device that was previously configured for DynDNS at NovaDNS by changing the server hostname. No client software changes required.
Post-acquisition, DynDNS is aimed at large enterprises that need managed DNS infrastructure at scale. If you are an individual, home lab enthusiast, or small business, DynDNS is not the right tool. NovaDNS was built specifically for that audience.
Verdict
DynDNS is a historical giant that priced itself out of the market it created. If you were a DynDNS user forced to migrate, NovaDNS offers the same protocol compatibility, a modern interface, and plans that are actually accessible.
