What Is DynDNS
DynDNS, originally known as Dynamic DNS and later Dyn, is a managed DNS and traffic management platform now owned by Oracle as part of Oracle Cloud Infrastructure (OCI). Acquired by Oracle in 2016 for $600 million, Dyn was one of the earliest and most well-known dynamic DNS providers, helping users with changing IP addresses maintain consistent hostname resolution.
Dyn's dynamic DNS service was the original reason most people knew the name. It allowed users with home internet connections that had changing IP addresses to host services (web servers, game servers, VPNs) under a stable hostname. The free tier of this service became incredibly popular and was discontinued in 2014, leading many users to seek alternatives.
Today, Dyn operates primarily as an enterprise managed DNS and traffic management solution under Oracle. The consumer free dynamic DNS service is no longer available.
History and Oracle Acquisition
Founded in 2001 as DyName, Dyn pioneered the concept of dynamic DNS for consumers. The company grew to serve enterprise customers with managed DNS, email delivery, and traffic management solutions. In 2016, Oracle acquired Dyn for $600 million, integrating its DNS infrastructure into Oracle Cloud. The 2016 Dyn DDoS attack, which disrupted major internet platforms, highlighted both Dyn's importance to the internet infrastructure and the vulnerability of centralized DNS services.
