About DNS

The domain name system (DNS) is the mechanism used by hosts to resolve names on the Internet, and on some private networks as well. Hosts that participate in the DNS system have names like “www.tridium.com”. This is referred to as the fully qualified domain name. These names must be globally unique so the data intended for that domain is accurately routed. To accomplish this, the domain names are controlled by ICANN, and governed like the IP address system with authority granted to accredited name registrars located throughout the world.
