Use the DNS Configuration View to
resolve names to IP addresses via the Domain Naming System (DNS).DNS allows the router to resolve hostnames. This can be useful in helping to interpret the results of some diagnostics commands, but cannot be used in filter specifications.
The Domain name is the name that will be put at the end of all DNS searches if they fail. It will also be stripped from output.
When resolving hostnames, the Primary server will be consulted first, followed by the secondary and tertiary servers in case of failure or timeout. If present, the entries each must be an IP address of a host running a DNS server.
To present the DNS Configuration View, click the DNS link in the System Configuration section of the Config Tool main menu. The following figure shows an example of the DNS Configuration View.
