Configuring DNS Settings

References to SonicOS/X indicate that the functionality is available in both SonicOS and SonicOSX.

The Domain Name System (DNS) is a distributed, hierarchical system that provides a method for identifying hosts on the Internet using alphanumeric names called fully qualified domain names (FQDNs) instead of using difficult to remember numeric IP addresses. Network | DNS allows you to manually configure your DNS settings, if necessary.

The options in Network | DNS > Settings change depending on whether you select IPv4 or IPv6 on the Settings tab.

To select the IP version

1. Navigate to Network | DNS > Settings.
2. On the Settings tab, select either the IPv4 or IPv6 option.
