DynDNS - Dynamic DNS Pioneer

DynDNS (dyndns.org) is one of the original dynamic DNS services, founded in 1998 in New Hampshire, USA. The service allows users to map easy-to-remember hostnames to dynamically changing IP addresses, making it popular for home servers, remote access, security cameras, and IoT devices.

Services

Dynamic DNS - Hostnames that track changing IP addresses (e.g., yourname.dyndns.org)
Standard DNS - Managed DNS hosting for personal and small business domains
100+ domain options - Including .dyndns.org, .dvrdns.org, .dyndns.tv, .homeip.net, .selfip.com

History & Ownership

DynDNS was acquired by Oracle Corporation in 2016. The service continues to operate under Oracle's infrastructure, with the main dyn.com domain now redirecting to Oracle's corporate site. The free tier was discontinued in 2014, with paid plans starting at around $55/year.

The company gained notoriety in October 2016 when it was the target of a massive DDoS attack using the Mirai botnet, which disrupted major websites including Twitter, Netflix, and Reddit.
