Resolving DNS Issues on a Vizio


While network devices establish communication through unique numerical addresses, servers are usually assigned a name to make networking more user-friendly. The Domain Name System, or DNS, is needed to translate the name of a domain to its actual numerical address. As with all network capable devices, your Vizio equipment must have an ability to resolve domain names to establish connectivity. If you are having DNS-related problems with your Vizio device, resolve the problem by manually assigning the server information.
